基于FME的基础测绘数据向GIS格式转换的研究
|
摘要
鉴于DWG格式到SHAPE格式转换存在图形不整齐与属性丢失的问题,该文基于数字城市部件普查项目,探讨了由原始CAD城市基础测绘数据向GIS中SHAPE格式转换的具体原理与方法。对GIS数据库建设中遇到的实际问题予以分析,解决了异构数据的同化难题,很好地避免了图形的不规范及其属性缺失的现象。基于Arc GIS建立了地形图符号库,为今后同类项目提供了较好地参考。
In view of the problems of graphic irregularity and attribute loss,when the DWG format converts to SHAPE format,based on the project of digital city components general survey,this paper discusses the specific principle and method of format conversion from the original CAD urban basic mapping data to the SHAPE of GIS. And the practical problems which encounter in the construction of GIS database are analyzed. The problem of heterogeneous data assimilation is solved,the phenomenons of graphic irregularity and attribute loss are avoided better. The symol library of topographic map based on Arc GIS is built,and it provides better reference for similar projects in the future.
