Abstract
A system is presented that utilizes the symbolic knowledge found in the legend of the map to drive geographic symbol recognition. The geographic symbol layer(s) of the map are first scanned. The legend of the map is located and segmented. The geographic symbols are identified and their semantic meaning is attached to them. The geographical symbols in input maps are classified using statistical pattern recognition. An experimental study was conducted on a large amount of data with recognition rates of over 95%
