DEVELOPMENT OF A UNIFIED MODEL OF GEOINFORMATION SYSTEM FOR CITY PLANNING AND INTEGRATION

On the basis of modern technologies, an information database of seismicity and seismic risks has been created in the information system designed for city planning which includes maps of detailed seismic zoning (DSZ) of the Republic of North Ossetia-Alania and the map of seismic microzonation (SMZ) of the territory of Vladikavkaz. Evaluation methods of social and economic losses from possible earthquakes of different intensity are considered and a methodology for seismic risk assessment is developed. An algorithm for introducing the methodology for seismic risk assessment into information systems designed for city planning is proposed on their basis. Developed system is easily modernized and is the basis of a modern constantly updated information database that combines the results of all directions of the city planning for the cities and populated areas of North Ossetia, and it can also include any information that has a spatial reference, which makes it possible to include organically these data to the Federal All-Russian Information System.
