| Abstract: | 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. |
