Spring fires 2020 in Russia: Results from participatory burned area mapping with Sentinel-2 imagery

The dataset contains information about all fires that occurred on the territory of the Russian Federation from January 1 to May 15, 2020, when the first peak of spring fires ends for most regions. The contours of the fires were obtained by visual interpretation of Sentinel-2 MSI medium resolution satellite images (10-20 m / pixel) in a combination of Infra-Red (11-8-2) and Natural Color (4-3-2) channels at a scale of 1: 10,000 to 1: 50,000. For a more accurate determination of the boundaries of the territories covered by the fire, the images before and after the fire were compared during visual interpretations. FIRMS thermal anomalies were used as an additional source of information. The digitizing process was carried out by trained volunteers, the verification was done by the GIS Unit experts of the Greenpeace Russia and contracted GIS specialists
