资源简介:

A vector map of fire perimeters of all forest fires in Sweden above 10ha from 2016 to 2022 and the Sala Megafire from 2014. Fires were detected using thermal anomalies from the MODIS spectrometer, post-fire images from Sentinel-2 (10m x10m resolution) of detected anomalies were manually examined using Sentinel Hub EO Browser as false colour composites (band combination Near Infrared – Red – Green) and image chips downloaded for fires over 10ha. Burned areas were then manually delineated in ArcGIS, unburned areas located within the fires were excluded from fire perimeters. Fire perimeters include areas burned that were not forest landcover, however fires which occurred on entirely non-forested land were excluded. The dataset is in vector (.shp) format with single part polygons representing burned areas; each associated with the date of the post fire Sentinel-2 images used to digitize the fire. This means that fire events with non-continuous burned areas are represented by several single-part polygons, which share the same Sentinel-2 image date.
