Building-polygon Simplification Based on Shape Matching of Prototype Template

We apply shape-number method to represent polygon shape and by least editing distance computes the shape similarity.The simplification of building polygon is conducted by replacing the original polygon with the matched template object.The method based on shape matching is an attempt of application spatial recognition in map generalization.The experimental results show that the matching similarity based on the shape-number calculating is consistent with human cognition able to be practically used in building generalization.
