AutoCAD与MAPGIS数据转换在工程地质中的应用

AutoCAD and MAPGIS Data Conversion in Engineering Geology Application

在地质灾害评价实际工作中,为了准确提取数据、方便绘图,结合AutoCAD(Auto Computer Aided De-sign)和MAPGIS(Map Geographic Information System)的基本特点,详细分析了两者图形数据特点和图形数据转换过程中需要注意的问题。重点阐述AutoCAD的DXF(Drawinge Xchange Format)和DWG(Drawing)两种图形数据格式与MAPGIS的MPJ(Mapgis Project)图形数据格式之间转换的实现过程与方法,从而使现有的地理信息资源得到充分利用,实现图形数据共享。

In order to extract accurate data for mapping in the actual work of evaluation of the geological disasters, with the combination of the basic characteristics of AutoCAD （Auto Computer Aided Design） and MAPGIS （ Map Geographic Information System） , we analyzes the characteristics of the two graphics data and the problems which should be paid attention to in the graphics data conversion process. The paper focuses on the process and methods in the conversion process between the AutoCAD DXF （Drawing exchange Format） and DWG （Drawing） two graphics data format and the MAPGIS MPJ （ Mapgis Project） graphical data format, so that the existing geographic information resources can be utilized sufficiently and graphics data can be shared.
