目前大多数现有的地形图都是基于CAD格式绘制、存储的，但是CAD格式在数据分析、管理和处理上受到限制，需要转换成GIS格式。本文对地形图从AutoCAD（．dwg）数据格式转换为MapInfo（mid/mif）GIS数据，从图层组织、数据要素管理和背景图形方面对各种方法进行了分析研究。

At present , most of the existing topographic maps are drawn , stored on the basis of CAD format .However , data analysis , management and treatment are limited to CAD data format .So data conversion is required .This paper analyzed different conversion methods of topographic map from AutoCAD ( DWG) data to MapInfo ( mid /mif) GIS data in the respect of layer organization , prop-erty management and background graphics .
