The `evidential reasoning' method originally developed by Dempster and Shafer appears to offer much potential as a suitable methodology for combining the information from diverse sources such as image classifiers, expert system rules and geographic data, in order to generate optimal classifications taking account of all available evidence. The JRC has developed an implementation of this theory in which the results from a standard spectral image classifier are combined with evidence from expert system rules. These rules are triggered by spatial factors extracted from the imagery and by geographic parameters extracted from a geographic information system. Initial experiments have shown that this method gives significant improvements in thematic map products.
