摘要
在测绘工作中,由于项目不同,测绘数据存在的坐标系统、数据格式等的不统一,给数据共享带来很大不便。本系统实现了从AutoCAD DWG到ArcGIS Shapefile数据文件的快捷无损转换,以及几种常见图形数据文件格式的互相转换及坐标系统的转换,具有较好的现实意义与广泛的应用前景。
In surveying and mapping work,surveying and mapping data of different project sometimes differ in coordinate system and data format,which is a big obstacle to data sharing.The system discussed in this paper realizes seamless and quick data conversion from AutoCAD DWG format to ArcGIS shapefile format,and the data conversion and coordinate conversion between several common image data format,which has a good practical value and wide application prospect.
