Abstract

Sunshading is a powerful tool for the enhancement of linear features in images. Given the azimuth and elevation of a source of illumination it calculates the reflectance from a surface (which is composed of the data to be interpreted). Linear features lying at 90o to the illumination azimuth are enhanced, while those that lie parallel to it become less apparent. It is a standard tool used in the interpretation of geophysical potential field data.
