Minimize FORMOSAT-2
Web Content Image
FORMOSAT-2 is an Earth imaging satellite of NSPO (National Space Program Office) of Taiwan with the objective to collect high-resolution panchromatic (2 m) and multispectral (8 m) imagery for a great variety of applications such as in land use, agriculture and forestry, environmental monitoring, natural disaster evaluation, and in support of research interests, in particular with the ISUAL (Imager of Sprites and Upper Atmospheric Lightning)instrument. Daily image coverage of Taiwan and the surrounding region is required.

Besides providing imagery for the domestic needs of Taiwan, the spacecraft is frequently being used to deliver high-resolution imagery for event monitoring (such as the coverage of the Tsunami in Asia on 26 December 2004 and thereafter, coverage of Hurricane Katarina in August 2005, coverage of Typhoons on the Pacific, coverage of earthquake regions, etc.).

The spacecraft is operating nominally as of 2012.
