| 摘 要： | 基于MAPGIS软件,利用扫描后的地形图光栅文件经配准后,在图形上输入点图元并导出其明码文件,提取明码文件中的x、y坐标从而实现点坐标的自动读取。作者给出了详细操作步骤,具有很强的可操作性。该方法主要用于化探及其他需大量读取地形图点坐标的工程。

| Abstract: | It is able to be achieved to match the raster image files,draw point objects in a drawing to export the drawing file to text file,and collect the x and y coordinates data from the text file with a text editor.This paper is to supply a detailed account on the operating process,which is quite feasible.The method can be applied in geochemistry and other projects requiring a lot of coordinate data from the relief maps as well. |
