AutoCAD图形文件到MAPGIS数据文件的转换工具的开发与实现

The development and realization of transform tool of AutoCAD graphic file to MAPGIS data file

为了实现AutoCAD图形数据在MAPG IS系统中的共享,本文分析了这两种软件系统所支持的文件格式,并在此基础上,详细介绍了在AutoCAD Ob jectARX、MAPG IS和V isual C++环境下开发和实现“AutoCAD图形文件到MAPG IS数据文件的转换工具”的基本原理和关键技术,利用该工具可以将格式为DWG的AutoCAD图形文件直接转换为MAPG IS点(*.WT)、线(*.WL)数据文件。

In order to share AutoCAD graphic data in MAPGIS system, this paper analyzes the format of those two kinds of software firstly.Then it gives a detailed introduction to the basic principle and key technology of how to develop and realize the transform tool of AutoCAD graphic file to MAPGIS data file,in the environment of AutoCAD Object ARX,MAPGIS and Visual C++.Finally,a conclusion is obtained that this transform tool could realize the transformation of AutoCAD DWG graphic file to MAPGIS point file(*.WT) and line file(*.WL).
