摘要
由于数字地形图数据模型与GIS数据模型存在差异性,导致了数字地形图不能直接被GIS使用。为了解决这一问题,本文通过ArcGIS提供的CAD导入工具首先将数字地形图导入到ArcGIS的Staging Geodatabase,然后利用C#和ArcObjects编程对Staging Geodatabase分类提取,实现了数字地形图入库工作。
Digital terrain map can＇t directly be used in GIS applications because of the difference between their data models. To solve this problem, firstly digital terrain map is inputted into ＂Staging Geodatabase＂ with ＂import from CAD＂ tool offered by AreGIS, then the data are took out from Staging Geodatabase through the programmed with C# and AreObjeets. Thus, digital terrain map is converted into Geodatabase successfully.
