A Method for Contouring of Grid Data Converted from Irregularly Spaced Data on a Personal Computer (2)

Principle of Total Minimum Curvature

Abstract

In this paper, we presented the principle and the BASIC program for converting irregularly spaced data to grid data, based on the Briggs (1974) 's principle of total minimum curvature (a method to find the surface which contains data points and has the minimum total curvature) . The converted grid data are contoured on the screen of a personal computer us i ng the subroutine *CONTOUR (Shiono et al., 1985a) .
