摘要
通过对CASS,ArcGIS数据格式的分析,结合FME强大的数据转换功能,本文提出了一种利用FME技术实现地形图数据主流的CASS DWG格式经由SHP格式转换为符合国标规定的ArcGIS Geodatabase(MDB)数据的一种新方法,实现了地理数据批量、无损、高效地转换入库操作。以某市的地形图数据为数据源,进行实验验证,结果表明利用FME的Joiner函数模型可同步实现数据的格式转换、地理要素编码转换、地理要素的重分类与分层、投影变换等操作,可有效解决制约地理空间数据集成与共享的多源数据格式不统一的技术难题。
By analyzing the data format of CASS and ArcGIS , combined with the powerful data conversion function of the FME soft-ware, this paper adopted a new method which converts the leading cass dwg format of topographic map data to the Geodatabase （MDB） of ArcGIS which accords with the national standard through the SHP format data with FME , making the geographic data plentifully , completely and efficiently converted into the geodatabase .Taking the topographic map data of a city as an example to conduct the ex-perimental verification , the result indicates that using the Joiner function model of FME can realize the data format and geographical elements encoding conversion、the geographical elements′reclassification、projection transformation and other manipulation work at the same time.It also can solve the technical problem that the multi -source data formats are incompatible which restricts the development of the integration and sharing to the geospatial data .
