Expression of Topological Relations between Simple Region and the Region with Double Holes
Based on Egenhofer et al.,research thought about topological relations between simple region and the region with double holes.Proposes the expression model to topological relation between simple region and the region with double holes.And obtains 86 topological relations through the restraint inspection.According to 8 topological relations transformation order between two simple regions,we can get conceptual neighborhood graph of 86 basic topological relations between simple region and the region with double holes.Transformation order and connection degree of each topological relations are helpful in spatial reasoning,forecast and change analysis.
