INTEGRATION OF THE GEOLOGICAL INFORMATION DATABASE IN THE SYSTEM OF GEOINFORMATION MODELING

Abstract

The article is devoted to the integration of the geological information database of Vladikavkaz into a specially developed system of geoinformation modeling. With the development of high technologies, various geoinformation systems are widely used to collect, store, analyze and graphically visualize spatial data and associated information about the objects represented in GIS objects. The engineering geological zoning map of the Vladikavkaz city territory, covering geological structure, hydrogeological conditions, lithology, morphology, tectonics, distribution of various soil types in the considered territory, was created at the Geophysical Institute. There are areas on the territory that are characterized by the different depths of pebbles or the thickness of clayey and loamy cover on pebbles, which is the main parameter determining the category of seismicity according to construction rules and regulations «SNIP-II-7-81*». On the basis of the analysis of physical and mechanical properties, a reliable differentiation of soil groups with various determining parameters characterizing the category of soils according to their seismic properties was carried out. This information is collected in a database of geological information, formed as a shapefile with spatial reference of each well. The developed database is used as a basis in the problem of geoinformation modeling. The geodetic information database of Vladikavkaz was integrated into the system of geoinformation modeling on the basis of open source software.
