LISS-III (Resourcesat)
Four-band passive optical multispectral imager flown on Resourcesat missions for land and vegetation observation.
LISS-III (Linear Imaging Self-Scanning Sensor 3) is a four-band passive optical multispectral imager developed by ISRO for the Resourcesat series of land observation satellites.[1][2] It provides medium-resolution imagery suited to regional land cover mapping, vegetation monitoring, and agricultural assessment.
The instrument records Green (555 nm), Red (650 nm), Near-Infrared (815 nm), and Shortwave Infrared (1625 nm) bands at 23.5 m spatial resolution with a 141 km swath, capturing scenes at 10-bit radiometric depth.[2][1] WMO OSCAR records the swath as 141 km; eoPortal documentation for Resourcesat-2 cites 140 km for the same configuration.[2][3]
LISS-III flies on Resourcesat-2 and Resourcesat-2A alongside the higher-resolution LISS-IV and the wider-swath AWiFS instruments, providing a middle-resolution tier within the three-sensor Resourcesat imaging complement.[1][3] Its four-band spectral coverage, including the SWIR channel, supports vegetation index computation, land use change detection, agricultural crop monitoring, and burned area assessments.[3]
