Extended symbolic projections as a knowledge structure for spatial reasoning

Part of the Lecture Notes in Computer Science book series (LNCS, volume 301)


In earlier work it has been demonstrated that symbolic projections can be used as a spatial knowledge structure. Here it will be shown how the basic language used in the symbolic projections can be extended. The motivation for this extension is the need for a means by which to perform spatial reasoning in, e.g. digitized images or maps.
