Glossary for Geospatial Science

multispectral images:� Images optically acquired in more than one spectral or wavelength interval.� Each individual image is usually of the same physical area and scale but of a different spectral band.� The MSS and TM sensors aboard the Landsat satellite both collect simultaneous multispectral images.� The TM sensor scans and stores seven individual images in spectral bands ranging from the blue wavelengths up to those in the thermal infrared.
