Abstract

We present a concept for representing uncertain topological relations and their derivation from uncertain sets, useful for spatial and temporal reasoning in GIS. The concept is based on the notion of a stochastic boundary of a geometric set and on tests performed to decide the validity of relations between the sets. It uses the power-function to derive the probabilities of the found relations. The concept is applicable to all questions where uncertain geometric queries or analysis have to be performed.
