Abstract: At present, most current application systems use independent description model of direction relations and topologic relations, they influence the precision of spatial reasoning and spatial expression. The ultimate aim of this paper is to work out a combined model for topologic relations and direction relations based on Voronoi diagram, so that spatial relationship can be described more integrated.
Key words: Voronoi diagram, topologic relations, direction relations, spatial relationship, combined model
