摘　　要：首先阐述了GRD网格法进行渐变色填充剖平图的基本原理,然后详细介绍了利用MAPGIS二次开发平台提供SaveDemToSurfGrd()函数,在Visual Basic下实现将测量数据转换成标准的GRD网格数据,并在MAPGIS影像处理模块中,将GRD文件转换成Msi影像文件,实现渐变色填充剖平图的程序实现过程,最后总结出该方法的优缺点。The paper introduces the general principle of GRD gridding method in drawing profiles map by graded color filling. Its’ programming process is utilizing SaveDemToSurfGrd( ) function supplied by MAPGIS on secondary development platform based on Visual Basic to realize the converting survey data to normal GRD grid data, and converting GRD grid data to MSI image file in image processing module of MAPGIS. The advantage and limitation of the method is also discussed in this paper.
