摘要：
The spatial database in GIS contains parts of topological relations between spatial objects. Those relations are foundation for GIS query and qualitative spatial reasoning. We have a research on the spatial data structure of GIS in this paper, and give the basic method to obtain topological relations between spatial objects from spatial database in GIS. Then, to combine the method with the combinative table reasoning of spatial topological relations, an algorithm for obtaining spatial topological relations is present. The validity of the algorithm is certified by the experiment in this paper.
