The article is devoted to the geological information database integration in the Vladikavkaz city into a specially developed system of geoinformation modeling. With the high technologies’ development, various geographic information systems designed for collecting, storing, analyzing, and graphically visualizing spatial data and the related information about the objects represented in GIS have become widespread. A map of the engineering-geological zoning of the Vladikavkaz city territory has been created at the Geophysical Institute, covering the issues of the geological structure, hydrogeological conditions, lithology, morphology, tectonics and the distribution of various types of soils in the territory under consideration. There are areas on the territory characterized by different depths of pebbles or thicknesses of clay and loam on pebbles, which is the main parameter that determines the seismicity category according to Building Codes and Regulations-II-7-81*. Based on the physical and mechanical properties‘ analysis, the reliable differentiation of soil groups with various determining indicators characterizing the soils‘ category by their seismic properties has been carried out. This information is collected in a database of geological information generated in the form of a shape file with spatial reference of each well. The developed database is used as a basis in the geographic information modeling task. Based on epyopen source software, the integration of the geological information database in the Vladikavkaz city into the geographic information modeling system has been performed.
