PROCESSING OF PLAN-PROFILE VISUALIZATION BY USING MATLAB

To improve the efficiency of drawing color plan-profile map,this paper proposed to complete the plan-profile map by using Matlab software to batch process profile data obtained from cutting contour maps on arbitrary direction in Surfer software, through data translation,scaling and rotation conversion etc.And the automatic drawing of color plan-profile map is achieved by finding out the position of zero-value along profile,making the positive segment drawn with the warm color, while the negative segment drawn with cool color, so that positive and negative area can be more obvious,Finally,by saving the results as *.bln type file format in Surfer software,which can be called directly in Surfer to form the base surface map,the purpose of superimposing color planprofile maps on contour maps or other geographic maps are achieved,which will facilitate the geological interpretation.
