GIS tools for analysis and modeling of emergency situations (on the example of fires in Volyn region)

Abstract

The analysis of remote sensing materials using geographic information systems and technologies is important for research and preventing adverse natural phenomena, such as fires. In our article, we gave examples of fire research using GIS. The simplest method is fire analysis using the FIRMS web service. This method does not require any prior skills and abilities, allows you to record the existence of a fire and generally estimate its scale. The Copernicus Browser service allows you to work with multispectral satellite images from Copernicus missions for fire detection and analysis. The most promising is the study of bands obtained mainly in the near infrared and shortwave infrared bands. The greatest opportunities for analysis and visualization are opened during the analysis of satellite images in GIS. Thus, the calculation of the normalized burn ratio allows estimating the long-term consequences of fires. Satellite data and maps of fire intensity are of great practical importance. They can help develop emergency rehabilitation and revegetation restoration plans after a fire. They can also be used to assess the likelihood of future impacts on burned areas from floods, landslides, and soil erosion.
