Many physical processes operating in the landscape are locally dependent on landscape geometry. The decription of surface geometry contained in a digital terrain model (DTM) offers the opportunity to objectively evaluate these processes using computer technology. Examples of DTM application, shown in this paper, demonstrate the high potential that DTMS have in terrain evaluation. As the cost of DTM capture continues to decline, it is likely that in the near future, DTMs will become more routinely used.
