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.
