[IP3-7-4-3] Topological features

Topological features characterize qualitatively the position of spatial objects relative to each other. There are different models for representing topological relationships. Calculus-based method, for example, allows us to model five topological relationships of two spatial objects: touch, in, cross, overlap, disjoint.
