Abstract
Remote sensing has as yet had a surprisingly small impact on the study of landforms, perhaps because the scale of observation has been considered inappropriate for the study of erosional processes which is the prime concern of modern Geomorphology. We argue here that imagery, in fact, has great potential for resolving longstanding critical problems in geomorphology, including the spatial dominance of various erosional processes, the relative importance of geological constraints, and the relevance of various models of longterm landform development.
