Inconsistency detecting and handling for road intersections based on topological relation analysis
摘要
Abstract
Due to road intersections'complex structure,road data are prone to problems and defects of inconsistencies.In order to solve the topological inconsistency problems of inter-sections in road network,the detailed investigation of the categories,description and ex-pression of inconsistency of road intersections based on topological relation models are per-formed.The topological relations between vertices and segments'buffers of road intersec-tions are analyzed closely with respect to the structural characteristics of intersections of road network,then a method of detecting inconsistency for road intersections based on structural topological relations is proposed.The method is implemented with Visual Studio 2008 and ArcEngine components.The experimental results show that this method detects inconsistencies accurately and efficiently,including conflicting vertices adj acent to other close roads at intersections,overshoots or undershoots of intersections vertex,etc.关键词
