| 摘 要： | 数字栅格图和数字线划图是可以低成本获取的两种数字地图,而DLG是目前最普遍的矢量数据格式,是GIS的主要数据来源。在缺乏专业矢量化软件的条件下,利用AutoCAD环境对DRG图像经纠正、缩放、加载坐标系统等过程后进行矢量化,是获取DLG数据的简单有效方法。

| Abstract: | Digital raster graphic(DRG) and digital line graphic(DLG) are two digital maps that can be taken cheaply, and DLG is a commonest data format now, it is the main data source of GIS. In case of lack on professional software, it is a effective way of DLG data taking after correcting, scale and loading coordinate system of DRG images by AutoCAD. |
