DGT (Direção-Geral do Território) is developing methods based on Artificial Intelligence to produce land cover maps and change detection based on intra- and inter-annual time series of Sentinel-2 satellite images and expert knowledge. The maps produced differ from DGT’s current Land Use and Land cover map (COS) in that they represent land occupation in 13 classes in raster format (10-meter pixels), while COS also represents classes of land use in vector format with a minimum mapping unit of 1 ha. The new maps have been called COSsim (simplified COS). The image shows a subset of COSsim2020 which is based on …
