Spatial and radiometric features

Spatial and radiometric features, useful for data mining and high level information extraction, will be defined and developed. They Will be constructed using: - radiometric characteristics - spectral characteristics - spatial or local parameters such as texture values, shape and geometric descriptors (lines detection, polygons, specific textures for cultivated fields, extraction of characteristics points – SIFT/SURF) etc. Features will be extracted from single images from the EO data collection (SENTINEL-1, SENTINEL-2, SENTINEL-3, LANDSAT, ENVISAT, MODIS, Planet and RapidEye) but if necessary, depending on the mining algorithms, they can be computed several sources of data.
