Research on the Defect Automatic Identification Methods of Vector Map Data
摘要
Abstract
As the base of map data quality checking software, defect identification methods of vector map data re-late to the correctness and efficiency of the map data quality control. By analyzing the defect characteristics of vec-tor map data, the map defect categories and contents were studied, and basic geometry algorithms for points, lines and surfaces were summarized. For different types of defects, the defect autoidentification methods were developed, such as geometric imperfection identification, properties defect identification, edge disconnection identification, metadata error identification. Also, composite rules of basic arithmetic operators were proposed, and the flexible and convenient function recombination were implemented, and the algorithms were validated by instance.关键词
