CHRIS acquires a set of up to five images of each target during each acquisition sequence, these images are acquired when PROBA is pointing at distinct angles with respect to the target. The source data are in CHRIS Level 1A LAND MODE 3: Full swath width, 18 spectral bands, nadir ground sampling distance 17 m. GeoTiff (32 bit) format, atmospherically corrected towards surface reflectance after Guanter et al., 2005, doi:10.1109/TGRS.2005.857915
