WEB-ORIENTED GEOINFORMATION SYSTEM OF FOREST FIRE DANGER ESTIMATION, ZHARIKOVA M. V., Candidate of Technical Sciences

Protection of forest from fires includes a wide spectrum of actions which is not limited only by jet measures, such as fire extinguishing. Protection of forests from fires is a set of the actions directed on reduction of negative influence of forest fires on natural resources, ecosystems, and also environment according to the purposes of the organisation supervising administration. Protection of forests from fires includes as traditional actions under the control over fire-dangerous conditions (revealing, fire suppression etc.), and more difficult actions (prescribed burnings, management of forest fuels, etc.). The primary goals of protection of forests from fires are the prevention of forest fires, their optimum suppression and liquidation of consequences. A prominent aspect in a cut of the prevention of forest fires are technologies and methods of their forecasting. Paper purpose is the description of the geoinformation approach to construction of system of protection of forests from fires which is a combination of probabilistic and empirical methods. Formula for an estimation of forest fire occurrence probability for j-th time interval of fire season is obtained using probability theory substantive provisions. Program realisation of system of protection of forests from fires represents the web-oriented geoinformation system developed by means of platform Django in programming language Python. For realisation of cartographical functions has been used framework GeoDjango which is built in module Django. For database creation the control system of databases PostgreSQL and its expansion PostGIS intended for storage in base of geographical data have been used. Web-oriented system allows to operate with the cartographical information. The program complex which is executed on a server, allows to obtain and visualise a number of the parameters characterising forest fire danger. Technologies of remote sensing of the Earth can be used for more exact and operative estimation of forest fire danger. Besides, device MODIS Terra/Aqua data can be used for an estimation of ground layer temperature of atmosphere at calculations of a complex meteorological indicator. The typical results showing possibilities of web-oriented geoinformation system on example of forested territory of the Proletarian forest area of the Kherson region of Ukraine are presented.
