Abstract :
Many papers on modeling uncertain or fuzzy spatial data are based on probability functions or fuzzy set functions. However, few of them specify how to actually compute these in a real system. This paper presents a way to use Delaunay triangulations to compute the values of such functions for uncertain spatial objects represented in a vector model. The paper also contains an algorithm that uses this Delaunay triangulation to compute the probability that two uncertain regions intersect.
