    Proba-1 CHRIS Level 1A

    CHRIS acquires a set of up to five images of each target during each acquisition sequence, these images are acquired when Proba-1 is pointing at distinct angles with respect to the target. CHRIS Level 1A products (supplied in HDF data files, version 4.1r3) include five formal CHRIS imaging modes, classified as modes 1 to 5: Mode Name Swath Spectral Bands Nadir ground sampling distance MODE 1   Full swath width 62 (773nm / 1036nm) 34m @ 556km MODE 2 WATER BANDS Full swath width 18 17m @ 556km MODE 3 LAND CHANNELS Full swath width 18 17m @ 556km MODE 4 CHLOROPHYL BAND SET Full swath width 18 17m @ 556km MODE 5 LAND CHANNELS Half swath width 37 17m @ 556km   Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service.
