In the light of characteristics of seismic interpretation and structural map, this paper deals with a mapping mode for quick production of structural contours by using various kinds of software, such as four processes for calculation of an XYZ data in Excel, automatic creation of a contour map using the gridding method in Surfer, completion of a more logical contour map in AutoCAD, and more perfect processing of the logical contour map in MapGIS. The mapping mode can help reduce the workload, avoid artificial errors, and realize the drawing of structural contours with high precision and efficiency. By producing grid files using five different gridding methods and comparing the results in practical application, this paper gives a quick overview of each gridding method and points out advantages and disadvantages of each method. The five Gridding methods include Triangulation with Linear Interpolation, Inverse Distance to a Power, Minimum Curvature, Radial Basis Function and Kriging. Under most circumstances, kriging is the selected default gridding method because it gives better results for most XYZ data sets. In addition, the merits of AutoCAD relative to MapGIS in editing and revising contours are emphatically discussed.
