| Abstract: | According to the requirement of vector map clipping,this paper discusses the current theory and method of the map clipping algorithm for vector map,and puts forward a universal algorithm of map clipping. It can process the points,lines and areas in the vector data.The result of the experiment indicates that the algorithm operates quickly,and has a good reliability. |
