摘要
基于FME软件对数据源分析、构建转换模型,实现数据的结构转换和内容转换,并通过调用FME函数完成要素属性赋值,建立拓扑关系,最终实现数字城市大比例尺DLG数据入库。与传统大比例尺DLG数据入库方式对比,工作效率有很大提高。
Based on FME software about analysis of the data sources, building conversion model, achieve structural transformation and content conversion data, and by calling the function and completing FME feature attribute assignment, establishing topological relations,achieve large-scale DLG data storage eventually. Comparing DLG with the traditional large-scale data storage mode ,the work efficiency has greatly improved.
