Graphic Presentation of Contours on the Stereo-Net

Abstract

In this paper, we presented the principle and the BASIC program for drawing contours for any function defined on a spherical surface, on the stereographic nets (the Schmidt's and the Wulff's nets), using a personal computer, as a special application of the subroutine *CONTOUR (Shiono et al., 1985) for contouring of grid data.
