Overview & HistoryFORMOSAT-2 SpecificationsPricing

For mapping projects requiring the most up-to-date information possible, FORMOSAT-2 is the winner.

Launched on May 21, 2004 from Vandenberg Air Force Base, CA by the National Space Organization (NSPO), FORMOSAT-2 is the first medium resolution satellite developed by the Taiwanese. FORMOSAT-2 features optical sensors with 2-meter (m) panchromatic and 8-m multispectral (i.e. blue, green, red and near-infrared/NIR) resolution. With an orbital height of 891 kilometers (km), FORMOSAT-2 offers daily revisits over any location within its fixed orbital track.
