When modeling fire situations, discrete cellular-automaton approaches, as well as geographic information systems (GIS) with the ability to store and visualize spatial information, are very effective tools. In the paper we describe the methods of cellular automaton modeling, which allows to expand the possibilities of studying the processes associated with the spread of the fire front. In order to use GIS as a means of cartographic visualization for the simulation results, a digital elevation model (DEM) of the terrain for the mountainous and coastal regions of the Krasnodar region was constructed and a technology for creating a 3D~terrain model of these territories was developed. For a model description of real computational areas, in this paper, we have constructed a digital terrain model of the territory of the Krasnodar region. We also edited the topographic foundation covering the territory of the Krasnodar region and consisting of 29~sheets of undesigned (in geographical coordinates) digital data in the ArcInfo coating format of a scale of 1:200,000. The cartographic representation of the territory of the Krasnodar region in the ArcView, constructed according to that data in the Gauss-Kruger projection, was divided into sections 10x10 km in size. We used ArcView tools to obtain the TIN and GRID representations of the terrain.
The combination of functions implemented in the author's algorithms with GIS functions for processing attributive and graphic spatial data will provide effective solutions for modeling a spatially distributed process.
