High informational content of application of space shooting for updating of information on water management objects is shown. Sources of obtaining information for GIS, including satellite pictures are described. Practice showed high informational content of application of space shooting for updating of information on water management objects.
Geoinformation modeling of the ecological potential of Baikalian Siberia.
The article discusses the theoretical and practical aspects of understanding of the ecological potential. A method of calculating the ecological potential on the basis of GRID-simulation and the analytic hierarchy process is represented. The purpose of the environmental capacity assessment is to give a general idea of human conditions, tocreate a natural-scientific basis for reasonable regional environmental policy, for the improving the resettlement system and social development, for the rational organization of work and leisure and public health.
The restoration of the borders of the object according to the shallow resistivity survey by the method of fuzzy clustering.
Zlobina A.G., Zhurbin I.V.
The article offers the estimation to select the α-cut, which is the optimal in defining the boundaries of the buried object in the ground on a map of the distribution of apparent resistivity by the method of fuzzy clustering of Fuzzy c-means. The offered estimation provides the given accuracy for the restoration of the boundary of the object. The results were confirmed by the computer simulation experiment and field studies.
Hidden equivalence of solution algorithms of inverse gravimetric and magnetic problems.
We consider classification of solution algorithms of inverse gravimetric and magnetic problems. As the main basis for comparison of different algorithms we take the quality and quantity of extracted information. It is shown that the mathematical theory of interpretation of potential fields can be divided into 3 principally different methods of inverse problem solutions.
Modelling of geodynamic objects in three-dimensional GIS.
Petrov V.A., Veselovsky A.V., Murashov K.Y.
The current stage of development of the mineral resource base of the country demands to create a coherent geodynamic pattern of the studied ore deposits. An additional source of information and means of processing and interpretation of data is the use of three-dimensional GIS for surround optical 3D modelling the transformation ofthe Earth’s crust geodynamic nature. Three-dimensional GIS represent holistic geodynamic pattern of the studied ore deposits in the terms of escalation of geophysical, climatic, social, environmental and other disasters.Volumetric visual representation of the irregularities of the Earth’s crust geodynamic nature allows to more accurately assessing the condition of the mineral deposits of the country. As an example of using the proposed approach, simulation results for building optical three-dimensional objects of gold fields of various type of morphology: vein and veinlet-disseminated (Verninskoe deposit) and vein (Irоkinda deposit).
The technology for creating 2D&3D models of the earth crust, which are fitted with each other by the gravitational and magnetic fields, in the GIS INTEGRO environment.
Grishina I.L, Malinina S.S.
This article describes a technology for creating 2D&3D models of the earth crust, which are fitted witheach other by the gravitational and magnetic fields. The main feature of the technology is the calculation of theSpearman’s rank correlation coefficient between the results of downward-continued gravitational & magnetic fields, and the following determination of the sub-horizontal gravitational-magnetic boundaries. The technology was applied to the construction of the density-magnetic models based on gravitational and magnetic fields for the oil & gas basins of Timan-Pechora and North Caucasus. The resulting models have been analyzed for the features of the areas structural and tectonic layout, as well asof the display of hydrocarbon deposits on both local and regional scales.
Development of information system of modelling emergency situations on flooding of the territory Khanty-Mansiysk Autonomous Okrug – Ugra on the basis of GIS technologies.
Makeev A.V., Malyshev I.I.
The information system of modeling emergency situations on flooding of the territory of Khanty-Mansiysk Autonomous okrug – Ugra and definition of the waterlogged objects at the level of municipality is presented within research work. The developed technologies showed the good accuracy of calculation, and use of the GISArc GIS tools allowed to achieve high speed of system for calculation of zones of possible floodings.
Geoinformation analytical game «Territory development management».
Geoinformation Analytical Game is designed for training of systems analysts, specialized in decision support in territory development management. During the game, participants are trained to plan alternative scripts for territory transformation and to choose the most effective strategy to achieve the objective, taking into account the available budget. The game is based on the methodology of comparison of formalized cartographic descriptions of the territory in the form of digital raster maps, whose elements are the names of the specified classes of the underlying surface ofthe Earth. The list of classes is determined by a classifier, which is designed to reflect the specificity of the natural resources and land usage. The technique allows not only to detect changes, but provides a quantitative assessment ofthe importance of the differences found with regard to the objectives of the territory development. A quantitative measure of the differences is calculated using special estimators. The game begins with the definition of the in itial conditions, which include: creation of the maps for source and target state of the territory, object classifier, land value array, operations table, game budget and evaluation functions for calculation of maps difference measures. The goal ofthe game is to transform the initial state of the territory to a target state. Each of the game turns involves choosing thebest script from several alternatives. Measure of the difference between the map, built as a result of this script, and amap of the target state is used as a criterion. The above version of the game has been tested in the Master course for systems analysts in International University of «Dubna».
