Abstract. Qualitative spatial reasoning (QSR) has many and varied applications among which reasoning about cartographic entities. We focus on reasoning.

Apr 5, 2016 · Today's post is the seventh in a year-long series called,”Computing Space,” which highlights new mapping technologies and new areas for cartographic innovation.

Missing: Topological Entities.

If f : X −→ Y is a cellular map, it induces maps Xn/Xn−1 −→ Y n/Y n−1 that commute up to homotopy with the topological boundary maps and so induce.
