Vague Regions
Abstract: In many geographical applications there is a need to model spatial phenomena not simply by sharp objects but rather through indeterminate or vague concepts. To support su...

Quantifying spatial prepositions: an experimental study
Many aspects of spatial language concerned with relationships between spatial entities are essentially vague. Current GIS technology provides very little support for dealing with ...

A Predication Calculus for Qualitative Spatial Representations
Spatial information is information bound to spatial entities such as regions. It is based on the spatial structure alone (the valley includes the field) or connects thematic predic...
