Burned Area Maps of Portugal contain fire scar perimeters for four consecutive years. The dataset includes five DXF vector files mapping all fire scars with an area of at least 15 hectares, derived from supervised classification of Landsat 5 Thematic Mapper imagery. The work was performed under the IGBP-DIS Regional Satellite Fire Data Compilation, with analysis by the Remote Sensing and Geographical Analysis Laboratory of DEF/ISA and the Direccao Geral das Florestas.
Data is in DXF (Drawing Interchange File) vector format; users require GIS or CAD software capable of reading ASCII DXF files for analysis.
