An expert system has been developed for land use mapping from SPOT imagery. The system combines multiple sources of evidence using the Dempster-Shafer theory of reasoning and allows evidence to be propagated at multiple levels in a land cover classification tree. A spatial context rule base has been implemented, allowing pixel classifications to be refined and generalised to yield improved thematic map products.
