Zatcercovny V. Models, methods and program-technical instruments of geo-informational support for decision making in systems of territory management

Existing informational systems of territory management have certain imperfections. Increase of efficacy of territory units management systems can be GIS, that should become the core of computer-aided system of territory management. For this a number of methods, models and program-technical instruments of geo-informational support for decision making in territory management systems were developed. The ways to fill in GIS with actual and exact data for making effective administrative decisions proposed and theoretically grounded. The approaches to overcome deficit of prompt provision of territory management systems with digital cartographic and attributive materials of the complete scale line was developed. The methodology of mathematical model creation for the tasks of geo-informational forecasting and monitoring in conditions of insufficient dependence of a task and rather high quantity of varying factors were worked out. The quality evaluation of functioning of complex of territory management system (CTMS) and GIS, and efficacy of GIS and CTMS implementation according to different criteria was executed. The methodology and mathematical models for the tasks of forecasting and monitoring by regional GIS in conditions of bad task dependence and rather high quantity of varying factors were developed. Functional components of system were worked out and they became a part of Chernihivska oblast GIS. Keywords: geo-informational system, geo-informational technologies, remote Earth sounding, spatial fragmentation, brightness, digital relief models, digital processing of images, entropy, pixel.
