摘要:Vectorization of raster data is very important in GIS. Adjacent vertices of vector graphics usually pass though the same vertical or horizontal straight lines after vectorization. This paper proposes a method based on making full use of this character mentioned before. First, the Latent important vertices will be found the and the zigzag will be eliminated. Second, the redundant vertices, which is very close to the adjacent vertexes, will be removed. After these two processes, we can get smooth vector lines obtained from vectorization rapidly
