Satellite imagery such as Landsat TM and SPOT provide multispectral images of the earth, some containing seven or more bands.
smap program is used to segment multispectral images using a spectral class model known as a Gaussian mixture distribution.
This mission obtained the first near global topographic map of the Moon, as well as the first global multispectral images of the lunar surface. This was followed by the Lunar Prospector mission in 1998.
Note: Landsat 7 also carries a panchromatic band (visible through near infrared) with 15-m resolution for "sharpening" of multispectral images.
A standard color display of multispectral image displays three bands, one each for red, green and blue. Satellite imagery such as Landsat TM and SPOT provide multispectral images of the earth, some containing seven or more bands.

SPOT 5, launched in 2002 has improved spatial resolution for both panchromatic (2.5 and 5 meter) and multispectral images (10 meter visible, 10 meter Near IR).
