基于FME的道路悬挂节点数据提取技术

Data Extraction Technology of Road Suspension Node Based on FME

为了提高道路数据拓扑处理的工作效率,减少处理过程中道路浏览的工作量,在分析原有道路数据的基础上,采用FME软件建立道路悬挂节点提取模型,并在山东省1∶10000基础测绘数据中提取道路中心线数据,利用该道路悬挂节点提取模型提取道路悬挂节点数据,通过道路悬挂节点数据来准确快速定位到需要进行拓扑处理的具体位置,结合最新遥感影像进行数据拓扑处理。经实践该方法自动化程度高、拓扑处理无遗漏、行之有效,对FME在数据拓扑处理方面的应用有一定的参考价值。

In order to improve the efficiency of road topology processing and reduce the workload of road browsing in the processing process,based on the analysis of the original road data,FME is used to establish the road suspension node extraction model,extract the road centerline data from the 1∶10000 basic surveying and mapping data of Shandong province,use the road suspension node extraction model to extract the road suspension node data,accurately and quickly locate the specific location that needs topology processing through the road suspension node data,and conduct data topology processing in combination with the latest remote sensing image.Through practice,this method has a high degree of automation,no omission in topology processing and is effective.It has a certain reference value for the application of FME in data topology processing.
