Recent years have been marked by the rapid development and spread of remote sensing (ERS) and geoinformation technologies. Satellite images are actively used as a source of information to solve problems in various fields of activity: cartography, municipal administration, forestry and agriculture, water management, inventory and monitoring of the condition of oil and gas production and transportation infrastructure, assessment of environmental conditions, search and forecasting of deposits minerals, etc. Geographic information systems (GIS) and geoportals are used to analyze data for the purpose of making management decisions.
As a result, for many higher educational institutions the task of actively implementing remote sensing and GIS technologies in educational process and scientific activities. Previously, the use of these technologies was required, first of all, by universities training specialists in the field of photogrammetry and GIS. However, gradually, as remote sensing and GIS technologies were integrated with various applied fields of activity, their study became necessary for a much wider range of specialists. Universities providing training in specialties related to forestry and agriculture, ecology, construction, etc., now also require students to be trained in the basics of remote sensing and GIS, so that future graduates are familiar with advanced methods for solving applied problems within their specialty .
At the initial stage educational institution planning to train students in remote sensing and GIS topics, it is necessary to solve a number of problems:
- Purchase specialized software and hardware.
- Purchase a remote sensing data set that will be used for training and scientific work.
- Conduct retraining of teachers on remote sensing and GIS issues.
- Develop technologies that will allow solving applied problems corresponding to the specialization of the university/department using remote sensing data.
Without a thoughtful and systematic approach, solving these problems may require significant time and material costs from the university. The simplest and effective method overcoming difficulties - interaction with companies that supply all the necessary software and hardware for the implementation of remote sensing and GIS technologies, which have experience in implementing projects for various sectors of the national economy.
An integrated approach to the implementation of remote sensing and GIS technologies at a university will be provided by the Sovzond company, which offers a full range of services, ranging from the supply of software and hardware, their installation and configuration, to the supply of remote sensing data, training of specialists and the development of technological solutions. The basis of the proposed solution is the Earth Remote Sensing Data Processing Center (ERDC).
What is TsODDZZ?
This is a set of software and hardware tools and technologies designed to receive, process and analyze remote sensing data and use geospatial information. TsODDSZ allows you to solve the following main tasks:
- Obtaining remote sensing data (satellite images).
- Primary processing of space images, preparation for automated and interactive interpretation, as well as visual presentation.
- Deep automated analysis of remote sensing data for the preparation of a wide range of analytical cartographic materials on various topics, determination of various statistical parameters.
- Preparation of analytical reports and presentation materials based on satellite imagery data.
The key component of the data acquisition center is specialized software and hardware that has broad functionality for working with remote sensing and GIS data.
TsODDZZ software
The software included in TsODDZZ is designed to perform the following work:
Photogrammetric processing of remote sensing data (geometric correction of images, construction of digital terrain models, creation of image mosaics, etc.). It is a necessary step in the overall technological cycle of processing and analyzing remote sensing data, ensuring that the user receives accurate and up-to-date information.
Thematic processing of remote sensing data (thematic interpretation, spectral analysis, etc.). Provides for the interpretation and analysis of satellite imagery materials for the purpose of creating thematic maps and plans, and making management decisions.
GIS analysis and mapping (spatial and statistical analysis data, map preparation, etc.). Provides identification of patterns, relationships, trends in events and phenomena of the surrounding world, as well as the creation of maps to present the results in a user-friendly form.
Providing access to geospatial information via the Internet and Intranet (organizing data storage, creating web- services with GIS analysis functions for users of internal and external networks). Provides for organizing user access from the internal network and the Internet to information on a given topic for a certain territory (satellite images, vector maps, attribute information).
In table Figure 1 shows the software usage scheme proposed by Sovzond, which makes it possible to fully implement all of the listed types of work.

For higher educational institutions, the Sovzond company offers favorable terms for the supply of software. The cost of individual licenses for a university is reduced by two or more times compared to commercial licenses. In addition, special sets of licenses are supplied for equipment in classrooms (Table 2). The cost of a license package for training for 10 or more seats is generally comparable to the cost of a single commercial license. The table below describes the license packages provided by various software providers.
Table 2. Software licenses
Quite a lot Russian universities already have positive experience in using software products from ITT VIS, ESRI Inc., Trimble INPHO within the framework of educational and scientific activity. Among them are the Moscow State University of Geodesy and Cartography (MIIGAiK), Moscow State Forestry University (MGUL), Mari State Technical University (MarSTU), Siberian State Geodetic Academy (SSGA), etc.
Hardware TsODDZZ
The data center hardware includes advanced technical means, allowing a higher educational institution to organize research, educational process, implement various methods of working both with information and with the trained audience. The hardware is selected taking into account the scale of the planned work, the number of students being trained and a number of other factors. The data center can be deployed on the basis of one or several premises and include, for example, a classroom, a remote sensing laboratory and a meeting room.
The following equipment can be used as part of the data protection center:
- Workstations for installing specialized software (in classrooms and departments).
- Servers for organizing the storage and management of geospatial data.
- Video walls for displaying and collective viewing of information (Fig. 1).
- Video conferencing systems for the exchange of audio and video information in real time between remote users (located in different rooms).
These tools not only constitute a productive hardware platform for performing remote sensing data processing processes, but also allow for effective interaction between user groups. For example, a video conferencing system and TTS hardware and software system can provide real-time transmission of data prepared by laboratory specialists and video images directly to a screen in a meeting room.
Remote sensing data supply
When deploying a remote sensing data center, one of the important issues is the acquisition of a set of remote sensing data from various satellites, which will be used to train students and carry out various thematic projects. The Sovzond company interacts with leading companies operating remote sensing satellites and supplies digital data received from spacecraft WorldView-1, WorldView-2, GeoEye-1, QuickBird, IKONOS, Resurs-DK1, RapidEye, ALOS, SPOT, TerraSAR -X, RADARSAT-1,2, etc.
It is also possible to deploy a ground-based receiving complex at the university, created with the participation of the Federal Space Agency (Roscosmos), providing direct reception of data from the Resurs-DK1, AQUA, TERRA, IRS-1C, IRS-1D, CARTOSAT-1 (IRS-P5) satellites ), RESOURCESAT-1 (IRS-P6), NOAA, RADARSAT-1,2, COSMO-SkyMed 1–3, etc. In addition, in the case of the deployment of DSDSRS, the Sovzond company provides the educational institution with a set of free remote sensing data from several satellites, having different characteristics (spatial resolution, spectral range, etc.), which can be used as test samples for teaching students.
Deployment of the Earth Remote Sensing Center in the Higher educational institution allows you to solve the problem of introducing remote sensing and GIS technologies into scientific and educational activities university and provide training for specialists in a relatively new and relevant area.
TsODDZZ is a flexible and scalable system. At the initial stage of creation, the data center can be a small laboratory or even separate workstations with remote sensing data processing functionality. In the future, it is possible to expand the data acquisition center to the size of large laboratories and training centers, the activities of which are not limited to teaching students, but also involve the implementation of commercial projects based on remote sensing data and the provision of information services to Internet users.
Remote sensing data provides important information that helps in monitoring various applications such as image fusion, change detection, and land cover classification. Satellite imagery is a key method used to obtain information related to earth resources and the environment.
The popular thing about satellite imagery data is that it can be easily accessed online through various mapping applications. By simply being able to find the right address, these applications have helped the GIS community in project planning, disaster monitoring in many areas of our lives.
The TerraCloud company provides access to a database of multi-temporal satellite images of the resolution you need from Russian satellites in one online window, around the clock and from anywhere in the world. And on convenient ordering conditions.
The main aspect that affects the accuracy of a ground object is spatial resolution. Temporal resolution helps in creating land cover maps for environmental planning, land use change detection, and transportation planning.
Data integration and analysis of urban areas using medium-resolution remote sensing imagery are primarily focused on documenting human settlements or used to delineate between residential, commercial and industrial areas.
Provides a base map for graphical reference and assistance to planners and engineers
The amount of detail that orthoimaging produces using high-resolution satellite imagery is significant. As it provides a detailed image of the selected area along with the surrounding areas.
Because maps are location-based, they are specifically designed to convey highly structured data and create a complete picture of where you want to go on the earth's surface. There are numerous applications of satellite imagery and remote sensing data.
Today, countries use information obtained from satellite imagery for government decision-making, civil defense operations, police services and geographic information systems(GIS) in general. These days, data obtained using satellite images, have become mandatory and all government projects must be submitted based on satellite imagery data.
During the preliminary and feasibility stages of mineral exploration, it is important to be aware of the potential mineral usefulness of the area being considered for mining.
In such scenarios, satellite remote sensing based mapping and its integration into a GIS platform helps geologists easily map mineral potential zones, saving time. Using spectral band analysis of satellite images, a scientist can quickly determine and display mineral availability using special indicators.
This will allow the exploration geologist to narrow geophysical, geochemical and test drilling to high potential areas.
The outcome of a natural disaster can be devastating and sometimes difficult to assess. But disaster risk assessment is essential for rescuers. This information must be prepared and executed quickly and accurately.
Object-based image classification using change detection (pre- and post-event) is quick way obtaining damage assessment data. Other similar applications using satellite imagery in disaster assessments include measuring shadows from buildings and digital surface models.
With the growing population around the world and the need to increase agricultural production, there is a definite need for proper management of the world's agricultural resources.
For this to happen, it is first necessary to obtain reliable data not only on the types, but also on the quality, quantity and location of these resources. Satellite imagery and GIS (geographic information systems) will always remain an important factor in improving existing systems collection and mapping Agriculture and resource data.
Agricultural mapping and surveys are currently being conducted around the world to collect information and statistics on crops, rangelands, livestock and other related agricultural resources.
The collected information is necessary for implementing effective management decisions. Agricultural survey is necessary for planning and allocation of limited resources among different sectors of the economy.
3D city models are digital models of urban areas that represent terrain surfaces, sites, buildings, vegetation, infrastructure and landscape elements, and associated objects belonging to urban areas.
Their components are described and represented with associated 2D, 3D spatial and georeferenced data. 3D city models support the representation, exploration, analysis and management of tasks across a wide variety of application areas.
3D GIS is a fast and efficient solution for large and remote places, where manual shooting is almost impossible. Various urban and rural planning departments need 3D GIS data such as, drainage, sewerage,
water supply, canal design and much more.
And a few final words. Satellite images have become a necessity in our time. Their accuracy is beyond question - because everything is visible from above. The main thing here is the question of the relevance of the images and the ability to get a photo of exactly the area of the territory that you really need. Sometimes this helps solve really important issues.
Characteristic feature The process of introducing geographic information technologies currently involves the integration of existing systems into more general national, international and global information structures. First of all, let's look at projects that are not even very recent. In this regard, the experience of developing global information programs and projects within the framework of the International Geosphere-Biosphere Program “Global Changes” (IGBP), which has been implemented since 1990 and has had a significant impact, is indicative. big influence on the progress of geographical and environmental work on a global, regional and national scale [V. M. Kotlyakov, 1989]. Among the various international and large national geoinformation projects, within the framework of the IGBP, we will only mention the Global Information Resource Database - GRID. It was formed within the structure of the Environmental Monitoring System (GEMS) created in 1975 under the auspices of the United Nations Environment Program (UNEP). GEMS consisted of global monitoring systems managed through various organizations UN, for example, Food and Agriculture Organization (FAO), World Meteorological Organization (WMO), World Health Organization (WHO), international unions and individual countries participating in the program to one degree or another. Monitoring networks are organized within five blocks related to climate, human health, ocean environment, long-range moving pollutants, and renewable natural resources. Each of these blocks is characterized in the article [A. M. Trofimov et al., 1990]. Climate-related monitoring provided data determining the impact of human activities on the Earth's climate, including two areas related to the work of the Background Atmospheric Pollution Monitoring network and the World Glaciological Inventory. The first concerns the establishment of trends in atmospheric composition (changes in the content carbon dioxide, ozone, etc.), as well as trends in the chemical composition of atmospheric precipitation. The Background Air Pollution Monitoring Network (BAPMON) was established by WHO in 1969 and has been supported by UNEP as part of GEMS since 1974. It includes three types of monitoring stations: basic, regional and regional with an extended program. Data are reported monthly to a coordination center located at the Intergovernmental Environmental Protection Agency (EPA) (Washington, USA). Since 1972, data together with materials from WMO and EPA have been published annually. The world glaciological inventory is associated with UNESCO and its Swiss Federal Institute of Technology. The information they collect is very important, since fluctuations in glacial and snow masses provide insight into the course of climate variability. The long-range transport pollution monitoring program is being implemented in conjunction with the work of the Economic Commission for Europe (ECE) and WMO. Data are collected on contaminated precipitation (in particular, sulfur oxides and their transformed products, which are usually associated with acid rain) in connection with the movement of air masses from sources of pollution to individual objects. In 1977, ECE, in collaboration with UNEP and WHO, formulated a joint program for monitoring and assessing the long-range transport of air pollution in Europe (European Monitoring and Assessment Programme). Monitoring related to human health provides the collection of data on global environmental quality, radiation, and changes in levels of ultraviolet radiation(as a consequence of the depletion of the ozone layer), etc. This GEMS program is largely related to the activities of the World Health Organization (WHO). Joint monitoring of water quality was undertaken by UNEP, WHO, UNESCO and WMO. The emphasis of the work here is on the waters of rivers, lakes, as well as groundwater, i.e. those that are the main source of providing people with water, for irrigation, some industries, etc. Monitoring of food contamination within the framework of GEMS has existed since 1976 in collaboration with WHO and FAO. Data on contaminated food products provide information about the nature of the spread of contamination, which, in turn, serves as the basis for management decisions of various levels. Monitoring of the ocean environment was considered in two aspects: monitoring open ocean and regional seas. The activities of the Renewable Earth Resources Monitoring Program are based on a preference for monitoring the resources of arid and semi-arid lands, soil degradation, and tropical forests. The GRID system itself, established in 1985, is an information service that provides environmental data to UN management organizations, as well as other international organizations and governments. The main function of GRID is to bring together data, synthesize it so that planners can quickly assimilate the material and make it available to national and international organizations making decisions that may affect the state of the environment. In its full-scale development at the turn of the century, the system was implemented as a global hierarchically organized network, including regional centers and national-level nodes, with extensive data exchange. GRID is a dispersed (distributed) system whose nodes are connected by telecommunications. The system is divided into two main centers: GRID-Control, located in Nairobi (Kenya) and GRID-Processor in Geneva (Switzerland). The center, located in Nairobi, oversees and manages GRID's activities worldwide. GRID-Processor is concerned with data acquisition, monitoring, modeling as well as data distribution. From global problems The Geneva Center is currently involved in the publication of the GEO (Global Environment Outlook) series of publications, the development of strategy and early warning of various threats, in particular to biodiversity (especially within the framework of the activities of the new DEWA - Division of Early Warning and Assessment), the use of GIS for rational use natural resources, specific studies, especially for French-speaking Africa, Central and of Eastern Europe, Mediterranean, etc. In addition to the two above-mentioned centers, the system includes 12 more centers located in Brazil, Hungary, Georgia, Nepal, New Zealand, Norway, Poland, Russia, USA, Thailand, Sweden and Japan. Their work is also carried out on a global scale, but to a certain extent is specialized by region. For example, the GRID-Arendal center (Norway) implements a number of programs in the Arctic, such as AMAP - Arctic Monitoring and Assessment Programme, the Baltic Sea region (BALLERINA - GIS projects for large-scale environmental applications), etc. Unfortunately, the activities of the GRID center -Moscow is little known even to specialists. Among the examples of international cooperation on the creation of large databases, the information system of the European Economic Community CORINE (Coordinated Information on the Environment in the European Community) deserves attention. The decision to create it was made in June 1985 by the Council of the European Community, which set two main goals for it: assessing the potential of community information systems as a source for studying the state of its natural environment and ensuring the environmental strategy of the EU countries in priority areas, including the protection of biotopes, assessment of air pollution as a result of local emissions and transboundary transfer, comprehensive assessment environmental problems Mediterranean region. To date, the project has been completed, but there is information about the possibility of its expansion to Eastern European countries in the future. Among national projects, naturally, I would like to turn to examples from Russia, although here we should immediately recognize that it is not the most advanced position in the world. Thus, in the early 90s, the possibilities of connecting the then USSR to work within the framework of the global natural resource system GRID UNEP were actively explored. We will indicate only one of the initiatives of that time within the framework of the activities of the Ministry of Natural Resources and Environmental Protection Russian Federation- a project for the creation of the State Environmental Information System (SEIS), the initial stage of which was developed in the former State Committee for Nature Protection of the USSR. It was planned that the GEIS would consist of durable databases; databases obtained during sub-satellite experiments and control measurements (apparently, temporary storage); database of a subset of data necessary for consumers to conduct research work, and from the information network connecting the system components with observation control centers and with bases of other systems, including international ones. The scope of application of GEIS, as conceived by the designers, was divided into the following main categories: 1) environmental control (to determine the state of the environment); 2) environmental monitoring (to analyze environmental changes); 3) modeling (for cause-and-effect analysis). GEIS in general view should have been computer system , in which the main source of information input is detailed databases of geographically oriented data on the state of the environment: images, operational control data, statistical observation data, series of maps (geological, soil, climatic, vegetation, land use, infrastructure, etc.). The joint processing of this information represents a direct path to environmental modeling. The main objective of the planned GEIS was to develop database management technology, combining environmental data sets that exist in multiple formats and taken from different sources. Data in the GEIS should have been received in the following subject areas: geosphere (including the earth's shells - atmosphere, hydrosphere, lithosphere, biosphere) and technosphere; material natural resources (energy, minerals, water, land, forest, etc.), as well as their use; climate change; state of production technologies; economic indicators in environmental management; waste storage and processing; social and medical-biological indicators, etc., naturally providing for the possibility of subsequent synthesis of indicators. In some respects, this program resembled the methodology used in the UNEP GRID system. Among the federal level programs, mention should be made of the GIS project of the OGV (Government Authorities), which began to be implemented in real life at the regional level (see below) or transformed for other needs, for example, the federal target program “Electronic Russia” (2002 - 2010) that began to be implemented. . As an example of complex systems, we point to the development of “Sustainable Development of Russia” [V.S. Tikunov, 2002]. A feature of its structure is the close linkage between the sociopolitical, economic (production), natural resource and environmental blocks. In general, they characterize socioecosystems of various territorial ranks. For all thematic subjects, it is possible to characterize the hierarchy of their changes - from the global to the local level, taking into account the specifics of representing phenomena at different scales of their display. Here the principle of hypermedia of the system is implemented, when stories are connected by associative (semantic) connections, for example, stories of a lower hierarchical level not only display a thematic story on an appropriate scale, but also, as it were, reveal, unfold, and detail it. At the top level of the hierarchy, a section “The Place and Role of Russia in Solving Global Problems of Humanity” was created. The world maps of this section are designed to display reserves, as well as the balance of production and consumption by humanity of the most important types of natural resources; dynamics of population growth; anthropogenic load index; the contribution of Russia and other countries to the planetary environmental situation, etc. Anamorphoses, diagrams, graphs, explanatory text and tables should show the role of Russia in solving modern global problems of humanity. It is useful to compare regions of Russia and foreign countries when they are considered as a single information array. For these purposes, multidimensional rankings were used based on complexes of comparable indicators, which, according to some integral characteristics, distributes Russian regions from the level of Austria (Moscow) to Nicaragua (Republic of Tuva). One such example of public health characteristics is shown in Fig. 24 colors on It shows the characteristics of public health in countries around the world and regions of Russia, but similarly the stories can be continued down to the municipal level. Sections at the federal level form the main core of the system. Along with many original stories, a fairly complete description of all components of the system is given. nature-economy-population» with an emphasis on the nature of the changes taking place. The blocks end with integral assessments of socio-demographic sustainability, sustainability of economic development, sustainability of the natural environment to anthropogenic influences and some other generalizing subjects, expressed quantitatively. The index of sustainable economic well-being and the index of human development, as well as the index of environmental sustainability, real progress, “living planet”, “ecological footprint”, etc. are widely known as integral characteristics [Indicators..., 2001]. But even when turning to particular subjects, not to mention complex characteristics, the task is not just to show the actual state, but to emphasize the patterns in the development of phenomena, to display them from different sides. As an example, let us point out the characteristics of election campaigns held in Russia since 1991. Thus, in addition to traditional plots showing the winners in election campaigns and the percentage of votes cast for a particular candidate or party, integral indices of territorial controllability are shown [V.S. .Tikunov, D.D.Oreshkina, 2000] and the nature of their changes from one election campaign to another (Fig. 2S color on). Another example of a non-traditional approach is the combination of typological and evaluative characteristics, such as the assessment of public health with the types of causes of mortality in the population (Fig. 26, color on). The next hierarchically lower section of the system is the block “Models of transition of Russian regions to sustainable development.” As in other sections of the Atlas, the main content of all branches of this block is aimed at identifying the environmental, economic and social components of sustainable development of territories. Here, by now, you can find examples of characteristics of the Baikal region, the Irkutsk region, the Irkutsk administrative region and Irkutsk. When characterizing the region, it will be analyzed, on the one hand, as an integral part of a larger entity - the state, on the other - as a self-sufficient (within certain limits) integrity, capable of self-development based on available resources. Based on the created maps, it is planned to develop proposals for the development strategy and innovative activity of the region and its territories. A typology of all regions of Russia was carried out and typical representatives were identified different groups(industrial, agricultural, etc.). It is planned to create several regional branches of the system, representing different types of territories of the country, in particular for the Khanty-Mansiysk Autonomous Okrug. Here you should pay attention to the principle of a block system, since individual logical blocks can be modified, replenished or expanded without changing the structure of the entire system. Topics related to sustainable development require mandatory consideration of almost all thematic subjects in dynamics, which is implemented in accordance with the principle of evolution and dynamism in the Atlas Information System. Basically, these are characteristics of phenomena over basic time periods or years. For a number of subjects, several thematic animations have been developed for retrospective analysis: “Changes in the arable land and forest cover of Russian regions over the past 300 years”, “Growth of the network of cities in Russia”, “Dynamics of population density in Russia, 1678-2011”, “Development metallurgical industry Russia in the XVIII-XX centuries." and “Development of the railway network (growth and electrification), XIX-XX centuries,” which constitute the first stage of the preparation of a comprehensive animation “Development of industry and transport” in Russia.” Essential Application systems - development of scenarios for the development of the country and its regions. In this case, the principle of multivariance is implemented, when the end user is offered a number of solutions that interest him, for example, optimistic, pessimistic and other scenarios. And the more complex these scenarios are, the more urgent the need for intellectualization of the system arises, when expert systems and the use of neural networks help in conditions of great complexity, often with significant vagueness of tasks, to obtain acceptable results. The use of meaningful modeling of complex phenomena within an information system is promising. The basis of such modeling is a comprehensive systems approach to modeling socioecosystems. Thus, the user of the system will be able to model a certain structure, the management of which will present options leading, for example, to increasing the level of well-being of the people or increasing their public health as the final result for many transformations with an assessment necessary expenses to achieve results. Simulation tools will be developed, primarily aimed at developing various scenarios for the transition of the country's regions to models of their Sustainable Development. The final stage of the project, associated with the intellectualization of the entire system, will allow the formation of a full-scale decision support system. Finally, it should be noted that the system being formed should also be based on the principle of multimedia (multi-medium), which facilitates the decision-making process. The creation of regional geographic information systems in Russia is largely associated with the implementation of the GIS Program of the OGV (Government Authorities) and the KTKPR (Comprehensive Territorial Cadastre of Natural Resources). The development of the main provisions for the GIS OGV program was entrusted to the State Center "Nature" - an enterprise of the Federal Service of Geodesy and Cartography (Roscartography). In a number of constituent entities of the Russian Federation, regional information and analytical centers equipped with modern computer technologies, including GIS technologies, have been created and operate. Among the regions in which the most significant results were obtained in creating the GIS OGV are Perm and Irkutsk region. In 1995-1996 significant work has been done to create a GIS Novosibirsk region. The most developed project in the field of regional GIS for the OGV is undoubtedly currently being implemented in the Perm region. "The concept of this system provides for the use of geoinformation technologies in structural divisions administration of the region and in structural divisions of government bodies of the Russian Federation operating in the territory of the Perm region. At the development stage, the concept was considered Federal service geodesy and cartography of Russia, as well as the State GIS Center and the State Center “Nature”. An agreement was concluded between the administration of the Perm region and the Federal Service of Geodesy and Cartography of Russia on the formation of a geographic information system of the Perm region, providing for the creation and updating topographic maps scales 1:1000,000 and 1:200,000 for the territory of the region. The concept of a geographic information system identified: the main directions for creating a GIS; composition of GIS users; database requirements; regulatory issues; GIS developers, development stages, priority projects, sources of financing. The main directions for creating GIS correspond to the directions management activities regional authorities: socio-economic development; economics and finance; ecology, resources and environmental management; transport and communications; public utilities and construction; Agriculture; . healthcare, education and culture; public order, defense and security; socio-political development. Naturally, a large place in the development of a regional system is occupied by providing the project with a digital cartographic basis. The concept provides for the use of maps: a survey topographic map at a scale of 1:1000,000 for the territory of the Perm region and adjacent territories; topographic map at a scale of 1:200,000 for the territory of the region; geological map at a scale of 1:200,000; topographic maps for areas of agricultural and forest lands, navigable rivers at scales of 1:100,000, 1:50,000, 1:25000, 1:10000; for solving engineering problems and urban management problems of maps and plans at scales 1:5000, 1:2000, 1:500. For maps, the coordinate system of 1942 was adopted. Maps made in the coordinate system of 1963 or in the local coordinate system, when included in the GIS of the region, are brought to a single coordinate system. For digital topographic maps, the Roskartorafiya UNI_VGM classifier is used, which provides the ability to work with symbol systems from a scale of 1:500 to a scale of 1:1000000 (all-scale classifier). The range of software used is quite wide: the LARIS project is carried out using software from Intergraph Sogr., the land committee up to the district level uses GIS MicroStation, some of the work is carried out in Maplnfo Professional, organizations of the Ministry of Natural Resources of the Russian Federation use Arclnfo, ArcView, ArcGIS, Geological maps are created in the GIS "PARK". Decisions on the choice of software tools were determined by the availability of established tasks in various departmental GIS and adopted industry decisions. The digital map formats used were determined by the GIS software used. However, it is indicated that it is necessary to have converters that convert digital maps from one format to another to ensure the transfer of information to various GIS packages. In November 1998, digital maps of the Perm region at scales of 1:1000,000 and 1:200,000 were transferred from the State GIS Center (Roscartography). The main format of the received maps is F20V. Maps are converted to the E00 format used in GIS by ESRI Inc. The information richness of the maps created by Roscartography did not suit the developers of the regional GIS. At the first stage, the developers of the system paid great attention to improving it, filling out the semantics of maps and territorial reference of existing and newly created thematic databases. During the creation of the GIS, several pilot projects were carried out: the creation of a comprehensive GIS of the village and resort “Ust-Kachka” to test complex solutions in a small area, using the example of the GIS “Ust-Kachka”, in order to demonstrate the capabilities of the GIS to insufficiently trained managers; creation of a flood model for the cities of Perm and Kungur. To create a flood model, a height matrix of the potential flood zone was constructed, and calculations were performed to model the flood level; development of environmental monitoring of GIS pilot projects for the city of Berezniki and surrounding areas. The main results of the program implementation are presented by the authors of the concept V.L. Chebykin, Yu. B. Shcherbinin in the form of the following subsystems (components): “GIS-geology”. It is being created for a real geological and economic assessment of the resource potential of the Perm region, developing solutions for the efficient use of resources. Includes a bank of geodata about mineral deposits, the location of mining and consuming enterprises, the amount of reserves, the dynamics of production and consumption; "GIS of land cadastre". Provides conditions for the objective collection of taxes on land and compliance with regulations on ownership, use, and change of owner. Includes a bank of geodata about the boundaries of land plots in the context of land ownership rights and a register of owners; "GIS roads". Allows you to determine and effectively use the technical and economic conditions for the operation and development of the transport road network. Based on a bank of geodata about the roads of the Perm region, the quality of the surface, the technical condition of the roads, the technical characteristics of bridges, driveways, crossings, ferry and ice crossings, and road signs.

As a result of the implementation of the program, legal, economic, organizational and technical measures should be developed and implemented to fulfill the tasks of creating a GIS OGV, databases of digital maps of the Perm region of various scales should be formed to display the dynamics of the socio-economic development of the region. The regional management structures will be provided with real spatiotemporal information about the infrastructure and social development of the region, which will allow the formation of a mechanism for managing the regional economy on a geoinformation basis. The developed concept of a geographic information system and the GIS creation program are based on the significant experience of enterprises and organizations of the Perm region in this field of activity. Various projects are being carried out in the Land Cadastre Committee of the Perm Region, the Perm State Geological Survey Enterprise "Geokarta", the Natural Resources Committee of the Perm Region, the Research Clinical Institute of Pediatric Ecopathology and other organizations. Under the leadership of the Land Cadastre Committee of the Perm Region, work is underway to conduct cadastral surveys, produce planning and cartographic materials, conduct a land inventory, and register land owners. The customer of the state automated land cadastre system in the Perm region (GAS ZK) is the Regional Land Cadastre Committee. Special working groups for the operational management of the implementation of the LARIS project have been created in the regional land committees and city district land committees. At the unitary state enterprise “Ural Design and Survey Enterprise for Land Cadastral Surveys” (“Uralzemkadastr survey”), specialized production based on digital cadastral technologies has been created. GIS from Intergraph Sogr., as well as MicroStation and Maplnfo Professional are used. The Perm State Geological Survey Enterprise "Geokarta" carries out work under the state geological mapping program. Each batch of the enterprise is assigned duty on one or two nomenclature sheets of a map of the Perm region on a scale of 1:200,000, the results of the work are presented in graphical and digital form. The enterprise uses the Geomap GIS, which provides technology for creating digital maps, as well as Arclnfo, ArcView, PARK 6.0. The following geological documents were created in digital form: Geological map of pre-Quaternary formations based on materials from further study and preparation of the state geological map at a scale of 1:200,000. Geological map of Quaternary deposits. Scheme of geomorphological zoning. Map of productive oil and gas bearing structures. Scheme administrative division with transport routes and main communications. The map of pre-Quaternary formations is supplemented with historical information: on copper, iron, chromite, bauxite, manganese, titanium, lead, strontium, gold; ' By building materials(gabbro-diabase, limestone, dolomite, marble, sandstone), quartz, fluorite, Volkon-ite; on oil, gas, coal, potassium salts, drinking water. The map of Quaternary deposits reflects the distribution by area of objects containing: gold, platinum, diamonds; agricultural ores (peat, calcareous tuff, marl), clays, sand and gravel mixtures, sands, etc. In pursuance of the order of the governor of the Perm region dated November 9, 1995 No. 338 “On the system of environmental monitoring in the region” under the leadership of the Committee of Natural Resources of the Perm region (formerly the State Committee for Environmental Protection) work is underway to create a Unified Territorial Environmental Monitoring System (UTSEM) for the region. ETSEM is created for the purpose of information support for making management decisions in the field of environmental protection to ensure environmentally safe sustainable development of the territory and is an integral part of the information and geoinformation system of the Perm region. Work on the creation and maintenance of a healthcare GIS was carried out by the Research Clinical Institute of Children's Ecopathology (NIKI DEP). At the regional level, the use of GIS has been developed to solve problems of information support for the regional health care management system: identifying territories with unfavorable trends in medical, demographic and medical-ecological indicators; justification of regional investments in territorial healthcare based on geoinformation analysis of medical and demographic indicators (both individual and complex); analysis of the adequacy of medical services to the population by territory and assessment of the severity of the problems of individual territories; justification and placement of a network of inter-district centers for the provision of specialized medical care etc. Work has been completed to link spatial information and databases on medical care for the population, medical-demographic, sanitary-hygienic and environmental indicators on a single schematic map of the Perm region. Information has been collected on more than 260 indicators. The system uses small-scale vector maps (1:1000000). The software allows you to play a number of scenarios and select options for the optimal use of hospital beds and laboratory and diagnostic facilities in medical institutions. To solve medical and environmental problems using GIS, priority territories were identified based on a set of risk factors for public health and individual environmental indicators, spatial reference was made to long-term databases by sources harmful effects on environment. An environmental project was implemented as part of the municipal GIS of Perm, which is a component of the regional GIS. Based on a 1:25,000 vector map, layers were created: population morbidity by districts of the city of Perm, coverage areas of medical institutions. The system allows you to track the dynamics of morbidity over the past 6 years using 68 indicators. As part of the project, layers have been formed that reflect various aspects of the state of the environment (zones of soil contamination with heavy metals, the content of harmful substances in the atmospheric air based on the results of field observations, stationary sources of emissions of harmful substances into the atmospheric air with detailed characteristics of each source, land allotments of industrial enterprises with information on enterprise as a source of environmental pollution, the content of harmful impurities in biological environments children's population, etc.). Layers with a rich attribute base are used in analytical tasks. The created system provides a solution to the problems of forming an optimal network of placement of air quality control posts based on population health criteria, developing programs for medical and environmental rehabilitation of children, etc. The environmental project of the municipal GIS is based on ArcView. GIS is used in combination with modeling and analytical programs, which makes it possible to obtain comprehensive assessments of various territorial levels. In 1994-1997 NIKI DEP released a medical and environmental atlas of the Perm region. In 1998, NIKI DEP together with the regional center of new information technologies of the Perm State technical university and the Department of Education and Science of the regional administration released an atlas of the social and educational sphere of the Perm region (a pilot project within the framework of the interuniversity scientific and technical program “Development of scientific foundations for the creation of geographic information systems”). By decision of the Legislative Assembly dated 04/06/98 No. 78, a comprehensive territorial program “Life safety and organization of monitoring systems for forecasting natural and man-made emergencies in the Perm region for 1998-2000” was adopted and implemented, providing for: Development and improvement of a geographic information system warnings and actions in emergency situations (GIS emergency situations); 2. Creation of a subsystem for actions in emergency situations as part of the geographic information system of the ATC of the Perm region. The emergency geographic information system is being created on the basis of research developments of the Mining Institute of the Ural Branch of the Russian Academy of Sciences (Perm).

Introduction
Geographic information systems (GIS) form the basis of geoinformatics - a new modern scientific discipline that studies natural and socio-economic geosystems of various hierarchical levels through analytical computer processing of created databases and knowledge bases.
Geoinformatics, like other Earth sciences, is aimed at studying the processes and phenomena occurring in geosystems, but uses its own means and methods for this.
As mentioned above, the basis of geoinformatics is the creation of computer GIS that simulate the processes occurring in the geosystem under study. To do this, you first need information (usually factual material), which is grouped and systematized in databases and knowledge bases. Information can be very diverse - cartographic, point, static, descriptive, etc. Depending on the goal, its processing can be done either using existing software products or using original techniques. Therefore, in the theory of geosystem modeling and the development of spatial analysis methods in the structure of geoinformatics, great importance is attached.
There are several definitions of GIS. In general, they boil down to the following: a geographic information system is an interactive information system that provides collection, storage, access, display of spatially organized data and is focused on the ability to make scientifically based management decisions.
The purpose of creating a GIS can be inventory, cadastral valuation, forecasting, optimization, monitoring, spatial analysis, etc. The most difficult and responsible task when creating a GIS is management and decision making. All stages - from collecting, storing, transforming information to modeling and decision-making in conjunction with software and technological tools are united under the common name - geo information Technology(GIS technologies).
Thus, GIS technologies are a modern systematic method for studying the surrounding geographic space in order to optimize the functioning of natural-anthropogenic geosystems and ensure their sustainable development.
The abstract discusses the principles of creating and updating geographic information systems, as well as their applications and applications. geographic information economic social
1 . General characteristics of GIS
Modern geographic information systems (GIS) are a new type of integrated information systems, which, on the one hand, include data processing methods of many previously existing automated systems (AS), on the other hand, have specifics in the organization and processing of data. In practice, this defines GIS as multi-purpose, multi-aspect systems.
Based on an analysis of the goals and objectives of various GIS operating currently, the definition of GIS as geographic information systems rather than as geographic information systems should be considered more accurate. This is also due to the fact that the percentage of purely geographic data in such systems is insignificant, data processing technologies have little in common with traditional processing of geographic data, and, finally, geographic data serves only as the basis for the solution large number applied problems, the goals of which are far from geography.
So, GIS is an automated information system designed for processing spatiotemporal data, the basis for the integration of which is geographic information.
GIS carries out complex processing of information - from its collection to storage, updating and presentation, in this regard, GIS should be considered from various perspectives.
As management systems, GIS is designed to support decision-making on the optimal management of lands and resources, urban management, transport and retail management, the use of oceans or other spatial objects. At the same time, cartographic data is always used among others to make decisions.
Unlike automated control systems (ACS), many new technologies for spatial data analysis are emerging in GIS. Because of this, GIS serve as a powerful tool for transforming and synthesizing a variety of data for management tasks.
As automated information systems, GIS combines a number of technologies or technological processes of well-known information systems such as automated scientific research systems (ASRS), computer-aided design systems (CAD), automated reference information systems (ASIS), etc. The basis for the integration of GIS technologies is CAD technologies. Since CAD technologies have been sufficiently tested, this, on the one hand, has ensured a qualitatively higher level of GIS development, and on the other hand, it has significantly simplified the solution to the problem of data exchange and selection of technical support systems. This is how GIS has become on a par with automated systems general purpose type CAD, ASNI, ASIS.
As geosystems, GIS includes technologies (primarily information collection technologies) of such systems as geographic information systems, cartographic information systems (CIS), automated mapping systems (ASC), automated photogrammetric systems (AFS), land information systems (LIS), automated cadastral systems (AKS), etc.
As database systems, GIS are characterized by a wide range of data collected using different methods and technologies. It should be emphasized that they combine both databases of conventional (digital) information and graphic databases. Due to the great importance of expert problems solved with the help of GIS, the role of expert systems included in GIS is increasing.
As modeling systems, GIS uses the maximum number of modeling methods and processes used in other automated systems.
As systems for obtaining design solutions, GIS largely use computer-aided design methods and solve a number of special design problems that are not found in standard computer-aided design
As information presentation systems, GIS is a development of automated documentation support systems (ADS) using modern technologies multimedia. This determines the greater visibility of GIS output data compared to conventional ones. geographical maps. Data output technologies allow you to quickly obtain a visual representation of cartographic information with various loads, move from one scale to another, and obtain attribute data in tabular or graph form.
As integrated systems, GIS is an example of combining different methods and technologies into a single complex, created by integrating technologies based on CAD technologies and integrating data based on geographic information.
As mass-use systems, GIS allows the use of cartographic information at the level of business graphics, which makes them accessible to any schoolchild or businessman, not only to specialist geographers. That is why when making decisions based on GIS technologies, they do not always create maps, but always use cartographic data.
As already mentioned, GIS uses technological advances and solutions applicable in such automated systems as ASNI, CAD, ASIS, and expert systems. Consequently, modeling in GIS is the most complex in relation to other automated systems. But on the other hand, the modeling processes in GIS and in any of the above AS are very close. The AMS is fully integrated into GIS and can be considered as a subset of this system.
At the level of information collection, GIS technologies include methods for collecting spatio-temporal data that are not available in automated control systems, technologies for using navigation systems, real-time technologies, etc.
At the level of storage and modeling, in addition to the processing of socio-economic data (as in automated control systems), GIS technologies include a set of spatial analysis technologies, the use of digital models and video databases, as well as an integrated approach to decision making.
At the presentation level, GIS complements ACS technologies with the use of intelligent graphics (presentation of cartographic data in the form of maps, thematic maps or at the level of business graphics), which makes GIS more accessible and understandable compared to ACS for businessmen, management workers, government officials, etc. .d.
Thus, in GIS, all tasks that were previously performed in the automated control system are fundamentally solved, but at a more high level data integration and fusion. Consequently, GIS can be considered as a new modern version of automated management systems that use more data and a greater number of analysis and decision-making methods, primarily using spatial analysis methods.
2 . Features of data organization in GIS
GIS uses a variety of data about objects, characteristics of the earth's surface, information about the shapes and relationships between objects, and various descriptive information.
In order to fully display geo objects real world and all their properties, an infinitely large database would be needed. Therefore, using generalization and abstraction techniques, it is necessary to reduce a lot of data to a finite volume that can be easily analyzed and managed. This is achieved by using models that preserve the main properties of the objects of study and do not contain secondary properties. Therefore, the first stage in the development of a GIS or the technology for its application is to justify the choice of data models to create the information basis of the GIS.
Choosing a method for organizing data in a geographic information system, and, first of all, a data model, i.e. method of digital description of spatial objects determines many of the functionality of the created GIS and the applicability of certain input technologies. Both the spatial accuracy of the visual representation of information and the possibility of obtaining high-quality cartographic material and organizing control of digital maps depend on the model. The performance of the system greatly depends on the way data is organized in a GIS, for example, when querying a database or rendering (visualization) on a monitor screen.
Errors in choosing a data model can have a decisive impact on the ability to implement the necessary functions in GIS and expand their list in the future, and the efficiency of the project from an economic point of view. The value of the generated databases of geographic and attribute information directly depends on the choice of data model.
Levels of data organization can be represented as a pyramid. A data model is a conceptual level of data organization. Terms such as “polygon”, “node”, “line”, “arc”, “identifier”, “table” refer to this level, just like the concepts “topic” and “layer”.
A more detailed look at the organization of data is often called data structure. The structure contains mathematical and programming terms such as “matrix”, “list”, “link system”, “index”, “information compression method”. At the next most detailed level of data organization, specialists deal with the structure of data files and their immediate formats. The level of organization of a particular database is unique to each project.
GIS, however, like any other information system, has developed means of processing and analyzing incoming data for the purpose of their further implementation in material form. In Fig. 3. A diagram of the analytical work of the GIS is presented. At the first stage, “collecting” of both geographical (digital maps, images) and attribute information is carried out. The collected data fills two databases. The first database stores cartographic data, while the second is filled with descriptive information.
At the second stage, the spatial data processing system accesses databases to process and analyze the required information. In this case, the entire process is controlled by a database management system (DBMS), with which you can quickly search for tabular and statistical information. Of course, the main result of GIS work is a variety of maps.
To organize the connection between geographic and attribute information, four interaction approaches are used. The first approach is georelational or, as it is also called, hybrid. In this approach, geographic and attribute data are organized differently. The connection between the two data types is through an object identifier. As can be seen from Fig. 3., geographic information is stored separately from attribute information in its own database. Attribute information is organized into tables controlled by a relational DBMS.
The next approach is called integrated. This approach involves the use of relational DBMS tools for storing both spatial and attribute information. In this case, GIS acts as a superstructure over the DBMS.
The third approach is called object-based. The advantages of this approach are the ease of describing complex data structures and relationships between objects. The object approach allows you to build hierarchical chains of objects and solve numerous modeling problems.
Recently, the object-relational approach, which is a synthesis of the first and third approaches, has become most widespread.
It should be noted that in GIS there are several forms of object representation:
In the form of an irregular network of points;
In the form of a regular network of points;
In the form of isolines.
Representation in the form of an irregular network of points is randomly located point objects that have some meaning at a given point in the field as attributes.
Representation in the form of a regular network of points is points of sufficient density evenly distributed in space. A regular network of points can be obtained by interpolation from irregular ones or by taking measurements along a regular network.
The most common form of representation in cartography is isoline representation. The disadvantage of this representation is that there is usually no information about the behavior of objects located between the isolines. This method representation is not the most convenient for analysis. Let's consider models for organizing spatial data in GIS.
The most common model for organizing data is the layer model. The essence of the model is that objects are divided into thematic layers and objects belonging to the same layer. It turns out that the objects of a separate layer are saved in a separate file and have their own identifier system, which can be accessed as a certain set. As can be seen from Fig. 6, industrial areas, shopping centers, bus routes, roads, population registration areas. Often one thematic layer is also divided horizontally - by analogy with separate sheets of maps. This is done for ease of database administration and to avoid working with large data files.
Within the layer model, there are two specific implementations: vector-topological and vector-non-topological models.
The first implementation is vector-topological, Fig. 7. This model has limitations: not all geometric types of objects can be placed in one sheet of one thematic layer at the same time. For example, in the ARC/INFO system, in one coverage you can place either only point objects, or only linear or polygon objects, or combinations thereof, excluding the case of “point polygonal” and three types of objects at once.
The vector-non-topological model of data organization is a more flexible model, but often only objects of one type are placed in one layer. geometric type. The number of layers in a layered data organization can be quite large and depends on the specific implementation. When organizing data in layers, it is convenient to manipulate large groups of objects represented by layers as a single whole. For example, you can turn layers on or off for rendering, and define operations based on how layers interact.
It should be noted that the layered data organization model absolutely dominates the raster data model.
Along with the layer model, an object-oriented model is used. This model uses a hierarchical grid (topographic classifier
In an object-oriented model, the emphasis is on the position of objects in some complex hierarchical classification scheme and on the relationships between objects. This approach is less common than the layer model due to the difficulty of organizing the entire system of relationships between objects.
As discussed above, information in a GIS is stored in geographic and attribute databases. Let's consider the principles of organizing information using the example of a vector model for representing spatial data.
Any graphic object can be represented as a family of geometric primitives with certain vertex coordinates, which can be calculated in any coordinate system. Geometric primitives differ in different GIS, but the basic ones are point, line, arc, and polygon. The location of a point object, such as a coal mine, can be described by a pair of coordinates (x, y). Objects such as river, water supply, Railway are described by a set of coordinates (x1, y2; ...; xn, yn), Fig. 9. Areal objects such as river basins, agricultural lands or polling stations are represented as a closed set of coordinates (x1, y1; ... xn, yn; x1, y1). The vector model is most suitable for describing individual objects and least suitable for reflecting continuously changing parameters.
In addition to coordinate information about objects, the geographic database can store information about the external design of these objects. This can be the thickness, color and type of lines, the type and color of the hatching of a polygonal object, the thickness, color and type of its borders. Each geometric primitive is associated with attribute information describing its quantitative and qualitative characteristics. It is stored in the fields of tabular databases, which are designed to store information of different types: text, numeric, graphic, video, audio. A family of geometric primitives and its attributes (descriptions) forms a simple object.
Modern object-oriented GIS work with entire classes and families of objects, which allows the user to gain a more complete understanding of the properties of these objects and their inherent patterns.
The relationship between the image of an object and its attribute information is possible through unique identifiers. They exist in explicit or implicit form in any GIS.
In many GIS, spatial information is presented as separate transparent layers with images of geographic features. The placement of objects on layers depends on each special case on the features of a specific GIS, as well as the features of the tasks being solved. In most GIS, information on a separate layer consists of data from one database table. It happens that layers are formed from objects composed of homogeneous geometric primitives. These can be layers with point, line or area geographical objects. Sometimes layers are created based on certain thematic properties of objects, for example, layers of railway lines, layers of reservoirs, layers of natural resources. Almost any GIS allows the user to manipulate layers. The main control functions are the visibility/invisibility of the layer, editability, and accessibility. In addition, the user can increase the information content of a digital map by displaying the values of spatial attributes. Many GIS use raster images as the foundation layer for vector layers, which also improves the visual clarity of the image.
3 . Methods and technologies for modeling in GIS
In GIS, four main groups of modeling can be distinguished:
Semantic - at the level of information collection;
Invariant is the basis for the presentation of maps, through the use of special libraries, for example libraries of symbols and libraries of graphic elements;
Heuristic - communication between the user and the computer based on a scenario that takes into account the technological features of the software and the processing features of this category of objects (occupies a leading place in interactive processing and in control and correction processes)
Information - creation and transformation different forms information in the form specified by the user (is the main one in documentation support subsystems).
When modeling in GIS, the following software and technology blocks can be distinguished:
Operations for converting formats and presenting data. They are important for GIS as a means of exchanging data with other systems. Format conversion is carried out using special converter programs (AutoVEC, WinGIS, ArcPress).
Projection transformations. Transition from one map projection to another or from spatial system to a map projection. As a rule, foreign software does not directly support projections common in our country, and information about the type of projection and its parameters is quite difficult to obtain. This determines the advantage of domestic GIS developments containing sets of necessary projection transformations. On the other hand, the various methods of working with spatial data that are widespread in Russia require analysis and classification.
Geometric analysis. For vector GIS models, these are operations for determining distances, lengths broken lines, searching for points of intersection of lines; for raster - operations of identifying zones, calculating areas and perimeter of zones.
Overlay operations: overlaying layers of different names with the generation of derived objects and inheritance of their attributes.
Functional modeling operations:
calculation and construction of buffer zones (used in transport systems, forestry, when creating protective zones around lakes, when determining pollution zones along roads);
network analysis (allows you to solve optimization problems on networks - path search, allocation, zoning);
generalization (designed to select and display cartographic objects according to scale, content and thematic focus);
digital relief modeling (consists in building a database model that best represents the relief of the area under study).
4 . Information Security
A comprehensive information security system should be built taking into account the four levels of any information system (IS), incl. and geographic information system:
The application software (software) layer responsible for user interaction. Examples of IS elements operating at this level include the WinWord text editor, Excel spreadsheet editor, Outlook email program, Internet Explorer browser, etc.
The level of the database management system (DBMS), responsible for storing and processing information system data. Examples of IS elements operating at this level include Oracle DBMS, MS SQL Server, Sybase and even MS Access.
The operating system (OS) level, responsible for maintaining the DBMS and application software. Examples of IS elements operating at this level include Microsoft Windows NT, Sun Solaris, and Novell Netware.
The network level responsible for the interaction of information system nodes. Examples of IS elements operating at this level include the TCP/IP, IPS/SPX and SMB/NetBIOS protocols.
The security system must function effectively at all these levels. Otherwise, an attacker will be able to carry out one or another attack on GIS resources. For example, to gain unauthorized access to information about map coordinates in a GIS database, attackers may try to implement one of the following capabilities:
Send packets over the network with generated requests to obtain the necessary data from the DBMS or intercept this data during its transmission over communication channels (network level).
In order to prevent this or that attack from being carried out, it is necessary to promptly detect and eliminate information system vulnerabilities. And at all 4 levels. Security assessment systems or security scanners can help with this. These tools can detect and eliminate thousands of vulnerabilities on tens and hundreds of nodes, incl. and remote over considerable distances.
The combination of using various security measures at all levels of GIS will make it possible to build an effective and reliable system for ensuring the information security of a geographic information system. Such a system will guard the interests of both users and employees of the company providing GIS services. It will reduce, and in many cases completely prevent, possible damage from attacks on the components and resources of the map information processing system.
5 . GIS Applications and Applications
Scientists have calculated that 85% of the information that a person encounters in his life has a territorial reference. Therefore, it is simply impossible to list all areas of application of GIS. These systems can be used in almost any area of human activity.
GIS are effective in all areas where the accounting and management of territory and objects on it is carried out. These are almost all areas of activity of governing bodies and administrations: land resources and real estate, transport, engineering communications, business development, ensuring law and order and security, emergency management, demography, ecology, healthcare, etc.
GIS allows you to accurately take into account the coordinates of objects and areas of sites. Due to the possibility of a comprehensive (taking into account many geographical, social and other factors) analysis of information about the quality and value of the territory and objects on it, these systems allow the most objective assessment of sites and objects, and can also provide accurate information about the tax base.
In the field of transport, GIS have long shown their effectiveness due to the ability to build optimal routes both for individual transportation and for entire transport systems, on the scale of an individual city or an entire country. At the same time, the ability to use the most up-to-date information about the state of the road network and capacity allows you to build truly optimal routes.
Accounting for municipal and industrial infrastructure is not an easy task in itself. GIS not only makes it possible to solve it effectively, but also to increase the impact of this data in case of emergency situations. Thanks to GIS, specialists from different departments can communicate in a common language.
The integration capabilities of GIS are truly limitless. These systems make it possible to keep records of the size, structure and distribution of the population and at the same time use this information to plan the development of social infrastructure, transport networks, optimal placement of healthcare facilities, fire brigades and law enforcement forces.
GIS allows monitoring the environmental situation and accounting for natural resources. They can not only answer where the “thin spots” are now, but also, thanks to the modeling capabilities, suggest where efforts and resources should be directed so that such “thin spots” do not arise in the future.
With the help of geographic information systems, relationships between various parameters (for example, soils, climate and crop yields) are determined, and locations of power grid breaks are identified.
Realtors use GIS to find, for example, all the houses in a certain area that have slate roofs, three rooms and 10-meter kitchens, and then return more detailed description these buildings. The request can be refined by introducing additional parameters, for example, cost parameters. You can get a list of all houses located at a certain distance from a specific highway, forested area or place of work.
A utility company can clearly plan repair or preventive work, from obtaining complete information and displaying on a computer screen (or on paper copies) relevant areas, say water supply, to automatically identifying residents who will be affected by these works, and notifying them of the timing of expected shutdowns or interruptions in water supply.
For satellite and aerial photographs, it is important that GIS can identify surface areas with a given set of properties reflected in the images in different parts of the spectrum. This is the essence of remote sensing. But in fact, this technology can be successfully applied in other areas. For example, in restoration: photographs of a painting in different areas of the spectrum (including invisible ones).
A geographic information system can be used to inspect both large areas (a panorama of a city, state or country) and a limited space, for example, a casino floor. Using this software, casino management staff receive color-coded cards that reflect the movement of money in games, bet sizes, pot draws, and other data from gambling machines.
GIS helps, for example, in solving such problems as providing a variety of information at the request of planning authorities, resolving territorial conflicts, choosing optimal (from different points of view and according to different criteria) places for placing objects, etc. The information required for decision-making can be presented in a concise cartographic form with additional textual explanations, graphs and diagrams.
GIS are used to graphically construct maps and obtain information about both individual objects and spatial data about areas, for example, the location of natural gas reserves, the density of transport communications, or the distribution of per capita income in a state. Areas marked on a map in many cases reflect the required information much more clearly than dozens of pages of reports with tables.
Conclusion
To summarize, it should be stated that GIS currently represents a modern type of integrated information system used in different directions. It meets the requirements of global informatization of society. GIS is a system that helps solve management and economic problems based on the means and methods of informatization, i.e. promoting the process of informatization of society in the interests of progress.
GIS as a system and its methodology are being improved and developed, its development is carried out in the following directions:
Development of theory and practice of information systems;
Study and generalization of experience in working with spatial data;
Research and development of concepts for creating a system of space-time models;
Improving the technology of automated production of electronic and digital cards;
Development of visual data processing technologies;
Development of decision support methods based on integrated spatial information;
GIS intellectualization.
