基于FME的道路连通性检测算法的实现

新一代地理信息数据库建设中新增的实体化编码和网络构建等数据深加工处理对入库数据中道路个体对象的连通性提出了更高的要求,常规测绘成果质量检查和现有相关研究对此未作特别关注。基于FME平台设计开发了顾及重复路段、细分不连通错误类型的道路个体对象连通性检测算法,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。

An Algorithm of Road Connectivity Checking Based on FME

Further processes such as object coding and network modeling in the construction of new geographic infor-mation databases put forward higher requirement to the connectivity of road object in the data to put in storage which has failed to attract special attention either from conventional quality inspection of surveying and mapping products or from relevant academic research. An algorithm of road object connectivity checking considering duplicate road segments and involving division of disconnection error types is proposed and implemented based on FME platform. Experiments with both simulated data and geographical conditions survey products demonstrate that the algorithm is accurate and robust.
