Aiming at planar moving points in the Euclidean space,based on 9I model,this paper defines spatial topological relations model of reference features,which is expressed as a triple of the topological relations at the three sequential times,describes the categorical topological relations between moving points and reference points,or reference features in lines and polygons.

In order to represent the equivalence of topological relations between a line and a region in vector space,on the basis of 97 topological relations between a line and a region,which are depicted by combinatorial reasoning of spatial topological relations,the questions of equivalent transformation of the basic topological relations types in abstraction process are discussed.

Research on spatial relation representation mainly includes spatial topological relation, spatial cardinal direction relation and spatial distance relation.

Equivalency evaluation model of spatial topological relations in multiple scale representation;

Queries of Spatial Topological Relations Based On Oracle Spatial;

The formalization and judgment of spatial topological relations plays important roles in modeling spatial data,spatial query,spatial analysis,spatial reasoning,updating spatial data.

When searching candidate matching collection for the current feature,a spatial query based on self-definition spatial topological relationship was designed,which narrowed the search scope,reduced the query time,and increased spatial analysis efficiency.

Formal description of the topological spatial relationship in GIS;

With development of GIS,people more and more realized to research spatial topological relations is very important.

One extended 4-intersection method of the topological relations description between a simple parcel and a parcel with one hole is proposed.

The theoretical foundation and application availability of topological spatial relationship research for three dimensional geo-entities in raster space are discussed.
