It is commonly recognized that free-hand sketch maps are influenced by cognitive impacts
and therefore sketch maps are incomplete, distorted, and schematized. This makes it difficult …

Qualitative spatial and temporal reasoning is based on so-called qualitative calculi.
Algebraic properties of these calculi have several implications on reasoning algorithms. But …

Buildings are man-made structures and serve several needs of society. Hence, they have a
