Ecological Systems and Devices Annotation << Back Structure of GIS-system for monitoring of forest fire danger caused Baranovskiy N.V. Yankovich E.P. By present time the method of prognostic modelling of forest fire danger which is based on probabilistic criterions and the deterministic models of ignition is developed. Among various sources of ignition probably to notable such factor as influence of the focused sunlight for layer of forest fuel. The further development of prognostic modelling has allowed to create a technique of classification of large forests on level of fire danger in the conditions of the focused sunlight without using of difficult mathematical models of forest fuel ignition. Creation information on the basis of the developed technique should become the further development in this direction. Logical for display spatial given to use technology of geoinformation systems. The structure of geoinformation system of an estimation of the forest fire danger caused by action of the focused sunlight is considered in present paper. The system combines a database on forest taxation descriptions of large forests, a quarterly map of a forest area and a layer of data of remote sensing of the Earth. The special attention is given structure of the system and algorithm of processing for taxation data with a view of an estimation and classification of forest sites by level of the fire danger caused by action of the focused sunlight.
