Description :
Landsat TM as well as SPOT HRV provides good possibilities for mapping of bedrock outcrop areas to be presented on the Swedish topographical map on the scale of 1 : 50 000. The errors of the computer-based classification can be reduced by a clean-up of the training areas, founded on level slicing with transformed spectral data. The mapping accuracy can be further improved by combining the automatic classification with a subsequent visual interpretation.
