Realization of the Extended Douglas-Pecucker Compressing Algorithm

WANG Jing, JIANG Gang-wu, GUAN Hua (Institute of Surveying and Mapping, Information Engineering University, Zhengzhou 450052, China)  
The article first discusses the classical Douglas-Pecucker Compressing Algorithm and analyses the reason of the graphics distortion phenomenon which is caused by applying the algorithm to the boundary data of the polygons. Lastly, the Extended Douglas-Peucker Compressing Algorithm is put forward, whereafter, the reliability of the algorithm is tested by the vector data from MapInfo.
