A Revised Contouring Program for Geological Use

Abstract

Shiono et al. (1985) 's BASIC program was revised in order to improve the efficiency of geological data processing. In addtion to change of contouring algorithm, two subroutines are added to the program: one is for drawing a frame of the display-area and a comment (*FRAME) and the other is for plotting two types of observed data (*PLOT.DATAI for normal xyz-data and *PLOT.DATA 2 for gologic data) . As observed data are displayed on the contour map, it becomes easy to compare the interpolation results with the original data which are used forthe interpolation.
