Extended Symbolic Projections as a Knowledge Structure for Spatial Reasoning.
Erland Jungert · Pattern Recognition · 1988
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.
