摘要
用SURFER的9种网格化模型分别绘制了等值线图,通过对比认为径向基本函数法对数据网格化后绘制的图形与手绘图形元素异常与分布趋势基本一致,作为地球化学图绘制的网格化模型效果最佳;提出了用采样点位图自动计算坐标—SURFER绘制等值线—MAPGIS处理成图的工作流程。
In this paper, contour diagrams are drawn with nine SURFER gridding methods. A comparison between contour diagrams drawn by hand and those by SURFER shows that Radial Basis Function gridding methods can be used in the drawing of geochemical contour diagrams. This paper also presents the flow chart for calculating the coordinate of MAPGIS-drawn contours in SURFER-processed Surfer plot files.
