Study of an Improved Building Polygon Simplification Algorithm

Abstract

Aiming to enhance the efficiency and accuracy of the simplification algorithm, this paper proposed an improved building polygon simplification algorithm based on the four-adjacent-point method. The interference of redundant points was excluded to avoid consuming operation; the classification of the basic processing unit was refined to avoid missing the processing of basic processing unit which has a special structure. Experiment result showed that the algorithm can take a better efficiency and accuracy, and it was more practical.
