Spatial relation is one of the most important features of geographic space information. The in-depth research on spatial relation is the base of realizing GIS spatial reasoning. Recently GIS software could only express few spatial relations and is difficult to be understood by computer, and also the researches on spatial relation ignore commonsense spatial cognition of people. The process on spatial...
Location is becoming kind of context fundamental information in ubiquitous computing environment. Location aware applications require a well-formed location model. Current location models can be classified into geometric location models and semantic location models. The former only represents the geometric coordinates without the location semantics.
