Abstract : This paper describes an approach for developing a three-dimensional (3D) landscape signature computer model. Primary focus is on thermal image generation using material temperature models and environment models for energy budget calculations. Current landscape signature models utilize one-dimensional conduction-calculations and constant meteorological data over large terrain areas. The model described here would compute thermal and other signatures using advanced 3D techniques where necessary to simulate higher resolution details necessary for such applications as sensor system evaluation.
