Abstract
A new method for extracting the variation in brightness due to topography (topographic component) from multispectral imagery is described. A lookup table relates multispectral brightness values within a training area to the topographic component computed from elevation data for a given reflectance model. The lookup table can then be used to determine the topographic component directly from the imagery in areas where elevation data does not exist
