Development of the prototype of a geo-information web system for dynamic visualization of forest fire hazard

Abstract

Abstract The article examines the prototype of an interactive system to display fire hazard in the forest during the fire season, prototype’s main characteristics and development methods of web GIS technologies. The proposed approach tracks changes in a special web map showing the state of fire danger in the forest based on the daily calculation of the fire hazard class under the current weather conditions. The analysis of data on forest types and frequency of fires proves that the calculations should include an increase in the natural fire hazard class concerning grass allotments in spring and autumn, as compared with summer. Changes in the weather conditions over time cause the map of a given area at a given point and time to change in accordance with the fire threats for these allotments. The developed interface for displaying the fire hazard data allows one to select the area under study and time range, as well as configure the data presentation template. The technological means used were the methods of Internet systems and geoportals producing geographic information, modern web technologies, libraries and services, including tools for dynamic representation of data of screen forms in web templates.
