Post-Fire Assessment of Burned Areas with Landsat-8 and Sentinel-2 Imagery Together with Modis and Viirs Active Fire Products
2020
This paper presents an unsupervised workflow to assess the extension of the burned areas due to wildfire events over green vegetated areas, in particular woods and forests, based on open access and high spatial resolution multispectral images from the Landsat-8 and Sentinel-2 satellites, together with open access high temporal resolution products (MODIS and VIIRS). The idea is to use jointly these kinds of data to combine the advantages linked to the use of high spatial resolution data with those ones derived from the exploitation of high temporal resolution data. Experimental results, carried on different case studies, show the effectiveness of the proposed method on forest fires, by reaching a performance in terms of the F-measure parameter, that ranges from 0.69 to 0.95, depending on the specific case study.
