Resolution for change detection&Blue band a plus
FORMOSAT-2 's spatial resolution — 2 metres in panchromatic (black and white) and 8 metres in multispectral (colour) mode — is an additional asset for surveillance. Ideally suited to strategic and operational intelligence missions, it is able to identify and characterize military sites, naval bases, air bases and refugee camps; perform reconnaissance of ships, aircraft and other assets; and surveillance of strategic or industrial facilities.
Like very-high-resolution satellites, FORMOSAT-2 has four bands: blue, green, red and near-infrared. Combined with the red and green bands, the blue band affords the ability to produce natural-colour composites without special processing. Used alone or with other channels, it also provides specific information for mapping shallow waters, distinguishing between bare earth and vegetation, mapping forests and identifying crops, and making atmospheric corrections.
