provides a “signature” for the type of vegetation present. To highlight different features of Earth, scientists combine images made in several broad wavelength bands (see Fig. 3). To create the composite image, colors are assigned to each wavelength band (see Table 1 and Fig. 3), and the result is called false-color. The more radiation reflected, the brighter the corresponding color in the image, and these colors are combined by addition, as in a computer monitor or color TV, to produce the image. A satellite

reflectance properties. The unique spectral properties of a land cover class are derived from a number of factors, including canopy geometry, leaf densities, colors, optical properties and moisture content, shadows, transpiration rates, and the properties of nonvegetated areas. Defined by the wavelength bands collected for the image analysis, these attributes are known as the class spectral signature. Classification of land cover types using spectral reflectance properties requires the use of a computer to handle the
