摘要：The Norwegian Computing Center has in collaboration withThe Norwegian Mapping Authority developed a semiautomaticprototype system for revision of some features in1:50.000 topographic maps based on pattern recognition inSPOT satellite imagery. The system generates a proposal fornew roads and new urban areas. Change detection isperformed in two main steps: In the first step the unreviseddigital map is used for detection of unchanged features in theimagery. In the second step, the features recognized in thefirst step are removed from the segmented data, and the newobjects are detected from the rest of the features. The revisionresult is used for updating the map data base for productionof "satellite revised maps". A satellite revised map isproposed as an intermediate map between the aerial photobased map revisions each 10th to 15th year.
