A Method of Spatial Conflicts Detection for Linear Objects Based on Topological Consistency
Qiang Zhang · 2011
Existing methods require comparing the spatial relations with well-defined rules to detect conflicts.However,some conflicts are usually undetected or detected by mistake because of incompletion of rules.Therefore,the types and causes of topological conflicts were analyzed firstly.Secondly taken topological conflicts between line objects as an example,the expression and calculation of topological relations,corresponding relation between lines before and after generalization,and a method of evaluating the consistency of topological relations which had been calculated were discussed.Finally,by verifing the consistency of corresponding topological relations,this method can detect topological conflicts which were undetected by existing methods.The results of experiment indicated that this method had good pertinence and accuracy.
