LISS-4

Linear Imaging Self-Scanning Sensor - 4

Satellites

IRS-P6 (ResourceSat-1) and ResourceSat-2

Status

Operational – Utilised in the period: 2003 to ~ 2013

Mission

Land and vegetation observation

Instrument type

3-channel VIS/NIR radiometer, one camera each channel

Scanning technique

Bushbroom, 4096 pixel/line per camera; swath 23.9 km if the 3 cameras are used each for 1 different channel (thus multi-spectral), or 70 km if all cameras are used for viewing parallel strips in the same channel (thus panchromatic). Cross-track pointing capability ± 26° for stereoscopy in between orbits

Coverage/cycle

Global coverage in 24 days, in daylight. 5 days for a target area by using cross-track pointing

Resolution (s.s.p.)

5.8 m IFOV
