A Relation-Based Merging Operator for Qualitative Spatial Data Integration and Conflict Resolution
Jan Oliver Wallgrün, Frank Dylla · 2010
We describe a distance-based approach to integrate spatial information from different sources that is given in the form of constraint networks over relations from a qualitative spatial calculus. The distance functions are based on the notion of conceptual neighborhood between the spatial relations. We opt for a merging approach that is relationbased instead of model-based and as a result is also able to relax inconsistent networks. We investigate the properties of the proposed merging operators and describe an algorithm for their computation.
