AVNIR-2 is a four band (visible and near-infrared) radiometer with a resolution of 10 m, designed for observing land and coastal zones. The images will provide the basis for land coverage and land-use classifi cation maps for monitoring regional environments. In addition, the instrument has a cross track pointing capability useful for quick response applications including disaster monitoring.
PALSAR is an L-band SAR with 10 and 100 m resolutions that are capable of detailed, all-weather, day and night observations and repeat-pass interferometry. PALSAR has a ScanSAR observation mode, with a swath (250-350 km) that is three to fi ve times wider than conventional SAR images. ScanSAR mode will be useful for monitoring sea ice and rain forest extent.
PRISM consists of three panchromatic telescopes for forward, nadir, and backwards viewing. The stereoscopic views will be used to create highly accurate digital elevation models, while the 2.5 m resolution will permit the production of orthorectified imagery.
