摘要：The theoretical foundations and application availability of topological spatial relationship research for three dimensional Geo-entities in raster space are discussed. The digital topology theory is applied to define the interior, boundary and k-order six neighborhood of a 3D geo-entity which is represented with regular hexahedron tessellation. A new 9-intersection model, which replaces the original interior I, the boundary B and the exterior E of an entity in 9-I model with I 6 , B 6 and E respectively, is presented. A computable method based on relation database query language SQL (Structured Query Language) is adopted for the model computation, topological query and analysis. The experimental analytic results show that the topology analysis model can be properly used for topological relations query and analysis of 3D Geo-entities represented in raster space, and it can also be applied for the reasoning of metric relation, direction relation and other spatial relationships
