摘　　要：利用FME中的语义转换技术,DWG数据可以与GIS SHP数据共享。实验以DWG水系设施数据为例,构建数字化DWG格式数据与GIS格式数据的映射关系表,并在此关系表的基础上,在FME workbench模型平台上构建水系DWG数据到GIS数据的转换模型。该模型实现了从DWG水系数据到GIS数据属性的无损转换,并对转换后的数据进行拓扑检查和属性数据整理。通过脚本程序对数据进行批处理,在很大程度上提高了数据入库的数据正确性、共享和转换效率。Using the semantic transformation technology in FME,DWG data can be shared with GIS SHP data.Taking the DWG river system facility data as an example,the mapping relationship table between digitization DWG format data and GIS format data is constructed.Based on this relationship table,the conversion model from river system DWG data to GIS data is constructed on the FME workbench model platform.The model realizes the lossless transformation from DWG river system data to GIS data attributes,and carries out topology inspection and attribute data sorting on the transformed data.Batch processing of data through script program greatly improves the data correctness,sharing and conversion efficiency of data warehousing.
