Russian drained peat bogs, hot spots 2002-2024 and analytics of this data.

Database for the operation of the Web resource https://peatfires.nextgis.com/, which is implemented within the framework of the program of the ANO "Center for the Prevention of Landscape Fires" to reduce the fire hazard of peat bogs.

The vector layer of the boundaries of drained peat bogs of this resource was created with the participation of volunteers and contains more than 13.5 thousand contours (polygons) of drained bogs. We also use a buffer 1 km wide from the boundary of the peat bog to display the current layer of thermal spots.

Peat bogs were identified by visual interpretation of satellite images based on a combination of features: characteristic drainage channels and the distances between them, former quarries of hydraulic mining and machine-molding peat extraction. The relief, hydrography, and signs of predominant vegetation were also assessed. In controversial cases, the history of drainage of a particular place was studied based on literary data.

Some contours may contain errors and inaccuracies in defining the boundaries in cases where at the time of creating the polygon there was no image of sufficiently high resolution.

2. Layer of hotspots

On the map, we show current MODIS and VIIRS hotspots within the contours of drained peatlands + a 1 km buffer zone. A hotspot in a contour gives reason to believe that there was an open fire of grass or forest on the drained peat, which could lead to the formation of smoldering soil foci.

Layers with historical hotspots since 2002 have been added. All hotspots are divided by year, season (spring and summer/fall) and types of satellite devices with characteristic errors.

Source of hotspot data: FIRMS

3. Automatically generated flammability indicators

Automatic graphs of the distribution of hotspots by years and seasons have been added. These graphs reflect the recurrence of fires, the probable transition of spring fires to summer fires within one year. In the case of spatial coincidence of thermal points in the fall of one year and in the spring of the next, it is possible to assume the presence of wintering smoldering centers.
