Spatial reasoning is a hot spot of artificial intelligence areas, and diffusely applied in areas such as geo-graphical information systems, robotic, high level vision, apprehends of natural languages, engineering design, andcommonsense reasoning about physical situations. This paper summarizes and discusses the represent ation of geometryof spatial objects roundly.
This paper first discusses some possible applications of qualitative spatial reasoning, then surveys the mainaspects of the representation of qualitative spatial knowledge including ontology, topology distance, orientation andshape.
