Image extraction, layerstack, radiometric calibration, normalization, mosaicking, automatic classification and segmentation could be easily performed while a user-friendly environment offers map editing and validation features. Based on open sources technologies, IMPACT relies on GeoExt, OpenLayers and Mapserver for the graphical user interface and raster/vector rendering; EO data processing is carried out by GDAL and Python. Single-date or multi-date segmentation is performed throughout Baazt segmenter libraries (Inpe’s TerraAIDA Operators).
