Formerly known as ROCSAT-2
FORMOSAT images are available through the Spot Image Corporation (http://www.spot.com/)
FORMOSAT-2 was launched in 2004 by the Taiwan National Space Organization. It has an orbit that is both geosynchronous, covering every place on earth once a day, and sun-synchronous, taking images under the same lighting conditions. Therefore, FORMOSAT-2 data are useful for change detection in rapidly changing landscapes. It carries panchromatic sensors (sensitive to all wavelengths in the visible spectrum, processed as a black and white image) and multispectral sensors (blue, green, red and near-infrared bands). Natural-color composites are available using red, green and blue bands without additional special processing. FORMOSAT has been used for mapping vegetation, various applications in crop science, and disaster management (eg. 2007 California wildfires, 2004 Indian Ocean tsunami, etc).
Other panchromatic/multispectral sensors include:
The image footprint is 24 x 24 km.
Image resolution is 2 m for panchromatic (black and white) FORMOSAT images and 8 m for multispectral (color) images.
FORMOSAT-2 images the same places on the surface of the earth at the same time every day. The high temporal resolution can be useful for detecting rapid change.
2004 to present.
FORMOSAT images are available from Spot Image. For a list of current pricing information, see http://www.astrium-geo.com/en/122-price-lists. Archived images over one year old cost half the price of current images. There are also options to acquire time series images at lower cost. Spot Image offers different pricing levels for standard licenses, purchased by for internal use by a single user, and multilicenses, purchased by multiple users for collaborative projects. Detailed licensing information is available at http://www.astrium-geo.com/en/886-legal-documents-and-supply-conditions.
FORMOSAT products are delivered in GeoTIFF format.
FORMOSAT images usually come in a user-friendly GeoTIFF format, which is preferred because of its easy integration with GIS platforms like ArcGIS and image processing programs such as Erdas Imagine and ENVI.
High spatial and temporal resolution FORMOSAT images were used to track rapidly burning California wildfires in 2007 (source: Liu et al. 2009).
ASTER and FORMOSAT-2 images classified into landcover types in and around Tianen City, Taiwan (source: Kato et al. 2008).
