PRACTICAL IMPLEMENTATION OF GEOGRAPHIC INFORMATION SYSTEM WITH SUPPORT FOR MODELING THE EFFECTS OF DANGEROUS NATURAL AND MAN-MADE PROCESSES

Abstract

On the basis of modern technologies developed structural-functional model «Information system for urban planning». This model is used as a basis for creating a modeling geographic information system. At the same time, an information database on seismicity and seismic risks is integrated into the system as a separate structural element, includes maps of detailed seismic zoning (DSR) of the Republic of North Ossetia-Alania and maps of seismic microzoning of the territory of settlements-administrative centers of the Republic of North Ossetia-Alania. The methods of estimation of possible social and economic losses from possible earthquakes of different intensity are considered and the method of seismic risk assessment is developed. On their basis, the algorithm of «introduction» of a technique of an assessment of seismic risk in information systems of providing town-planning activity is offered. The use of the developed methodology for assessing the seismic risk of the territory allows you to directly calculate the soil rating and seismic risk of the territory. On the territory of Vladikavkaz allocated areas with different soil conditions. Based on available data created the GIS project «Database of geological information of the Vladikavkaz city territory «, which includes information about wells drilled on the city territory and the composition of the respective soils. This database is integrated into the newly developed system, which allows to use it as one of the main sources of information in the problems of modeling the expected consequences of dangerous natural and man-made processes.
