We discuss description and reasoning over regions. We have proposed a system called SRCC that integrates integration of spatial and semantic data. SRCC can describe and reason abo...

Cavities in spatial phenomena require geometric representations of regions with holes. Existing models for reasoning over topological relations either exclude such specialized regi...

We investigate (quantifier-free) spatial constraint languages with equality, contact and connectedness predicates, as well as Boolean operations on regions, interpreted over low-...

We provide an algorithm that can construct a valid moving region from snapshots of a region in time. Our algorithm is robust in the sense that given valid input regions, the gener...
