【摘要】：针对测绘成果中入库数据道路实体连通性检测方面的问题,基于FME平台设计开发了一种道路实体连通性检测算法。该算法充分考虑了重复路段的情形,既适用于单线形结构的常规道路实体,也适用于三岔路结构的非常规道路实体,并且实现了对各种不同类型道路实体不连通错误的精细化检测。利用模拟数据和地理国情普查成果数据验证了算法的正确性与鲁棒性。所提算法为入库道路数据的连通性质量检查与修改提供了有力的工具,为数据库建设中道路数据的实体化编码和网络构建等数据深加工处理奠定了坚实的基础。
[Abstract]:A road entity connectivity detection algorithm based on FME platform is designed and developed to solve the problem of road entity connectivity detection of database data in surveying and mapping.The algorithm fully considers the case of repeated road sections, which is suitable for both the conventional road entities with a single linear structure and the unconventional road entities with a bifurcated road structure.It also realizes fine detection of disconnected errors of different types of road entities.The correctness and robustness of the algorithm are verified by using the simulated data and the data obtained from the GIS census.The proposed algorithm provides a powerful tool for the quality check and modification of road data connectivity in database construction, and lays a solid foundation for the further processing of road data in database construction, such as the materialized coding of road data and network construction.
