Management of Uncertain Spatial Information

Abstract

Spatial information is often associated with uncertainty and inaccuracy, and there is a growing recognition that this uncertainty must be represented and dealt with. In this paper, we present a new approach based on Dempster–Shafer theory for the representation and management of imprecision and uncertainty of qualitative spatial information. This approach is developed in the context of the Region Connection Calculus 8 (RCC8) and is applicable to geographical information systems (GIS), spatial databases and all applications that manage uncertain relationships between spatial features.
