ArcGIS、MapGIS及CAD矢量图形数据之间的无损转换方法与技术实现

Nondestructive conversion method and technical realization between ArcGIS,MapGIS and CAD graphic vector data

ArcGIS和MapGIS是目前国内地理信息系统广泛采用的GIS平台,已应用于国土管理、资源调查、规划等诸多领域。CAD是国内应用最广泛的绘图和设计软件,实现三者之间的数据格式转换对实际工作有重要意义。文章重点介绍了三款软件的功能及数据格式,阐述了ArcGIS、MapGIS和CAD数据转换的技术流程和方法,并结合“第三轮矿产资源规划”,详细阐述数据之间无损转换的方法以及若干应注意的问题。

ArcGIS and MapGIS are widely used GIS platforms in China,which have been used in many fields,such as land management,resource survey,planning and many other fields.CAD is the most widely used drawing and design software in China.There is a great significance to realize the data format conversion between the three platforms.This article mainly introduces the functions and data formats of the three softwares,expounds the technical processes and conversion methods of ArcGIS,MapGIS,and CAD data.With combination of"the third round of mineral resources planning",this paper expounds in detail for the method of nondestructive conversion between data and some problems that should be paid attention to.
