| Abstract: | The paper mainly discusses the auto creating technology of topological spatial relationship, on the basis of which a crunode matching algorithm is brought forward to create the topological relation of points and lines, and the topological relationship could be set up for points, lines and polygons based on grid index. Furthermore, the implementing process of auto creating of the Topological Spatial Relationship in GIS, is also presented in this paper. |
