Reasoning on Spatial Constraints over Regions
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...

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

On the Decidability of Connectedness Constraints in 2D and 3D Euclidean Spaces
We investigate (quantifier-free) spatial constraint languages with equality, contact and connectedness predicates, as well as Boolean operations on regions, interpreted over low-...

Spatial Reasoning with Integrated Qualitative-Metric Fuzzy Constraint Networks
Abstract: Qualitative Spatial Reasoning can be greatly improved if metric information can be represented and reasoning can be performed on it; moreover, modelling vagueness and unc...

Extracting moving regions from spatial data
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...
