Paper Abstract

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.
