The idea of Conceptual Neighbourhood Diagram (CND) has proved its relevance in the areas of qualitative reasoning about time...

A Refined Line-Line Spatial Relationship Model for Spatial Conflict Detection

0
In order to detect the spatial conflicts in the process of spatial database updating, a refined description of spatial...

Assessing Topological Consistency for Collapse Operation in Generalization of Spatial Databases

0
Generalization of spatial databases consists of complicated operations including not only geometric transformations but also topological changes. The changes...

Spatial Relations for Semantic Similarity Measurement
