Simplification and rectangularity of building-polygon based on least squares adjustment theory in map generalization

摘要：

This paper presents a method of building feature generalization through boundary division and line approximation according to Least Squares Adjustment theory.How to detect a point set and divide the segments is investigated in detail in the paper.Based on the Least Squares Adjustment theory with constraint conditions,the paper offers a model of rectangularity of building-polygon on condition that the sum of the squares of displacement distances of all points is minimum.These solutions have been realized in a software GenTool,which is an interactive map generalization software in real applications.
