Topological relations between discrete regions,ts in the vector model (?.) are investigated thoroughly, we run into inconsistencies in the raster model (?.). But instead of reducing our requirements in case of reasoning in raster images we change from simple raster to a cellular decomposition of ?. — what we call a hyper-raster — which is also d

Optimal redundancy in spatial database systems,we make use of this result to determine the optimal redundancy for real spatial data by means of theoretical considerations. In order to verify our theoretical results, we conducted several experiments using real spatial data and found a good correspondence.
