GIS model

Purpose. The aim of the research is to elucidate the regularity of the mudflow growth processes, depending on the factors that cause them and to the regional time-spatial prognostication of mudflow hazard using GIS. Methods. Using GIS technologies relevant and representative complex of significant factors due to the character of influence has been selected and suggested for usage in the regional prognostication of mudflows hazard. Geological, geomorphological, technological, climatic, landscape factors have been selected as spatial mudflow factors.

The paper presents a simulation model of the GIS representation of ground and air situation around the airport, which makes it possible to provide the necessary degree of detail of the processes of aircraft and other objects that move at the airport by a simultaneous transformation of their characters and plots geographic background, the presentation of electronic aeronautical charts observable part of space in a given scale
