| Abstract: | The analysis of topological spatial relationships is the foundation of GIS research. In the light of the problems probably occur in the determination of the spatial relationship between the point and polygon by using the ray casting theory, this paper puts forward the supplementary method, and from its extensions, obtain the solution for the determination of the spatial relationship between two simple polygons. |
