Representation and Reasoning about Spatial-Temporal Topological Relationships
Hongping Zhang · Geography and Geo-Information Science · 2010
Spatial object is the unit of space and time.Spatial-temporal topological relationship is composed of temporal topological relationship in time dimension and spatial topological relationship in spatial dimension.It is essential to study on spatial-temporal topological relationships in a unified framework.On the analysis of Allen′s 13 temporal topological relationships and Egenhofer′s 8 spatial relationships on regions,the integration framework for spatial-temporal topological relationships is proposed.In this paper,temporal topological relationships and spatial topological relationships are represented by 3×3 matrix respectively,so the authors proposed to use 3×6 matrix to depict spatial-temporal topological relationships.As many as 13×8=104 kinds of spatial-temporal topological relationships are illustrated.On the analysis of temporal topological relationships and spatial topological relationships reasoning,a spatial-temporal topological relationships reasoning method is proposed.Spatial-temporal topological relationships representation and reasoning method can be contributed to the research of spatial-temporal topological relationships.
