A Simplification of Residential Feature by the Shape Cognition and Template Matching Method

Abstract

Aiming at the typical template characteristics of building representation, this study built a series of templates to abstract the building shape by generalizing building polygons and analyzing the typical characteristics of regional environment.The shape description operator used the turn function method through the measure of the similarity between the building target and the template. From the perspective of shape cognition, this method conducted the building simplification by searching and matching the most similar template to replace the target building. The presented method is able to guarantee the overall shape structure unchanging and maintaining the area balance after the simplification. The experiments under real data show that the method holds high reliability and practicability, able to be widely applied to practical map generalization.
