In this paper, we presented the principle and the BASIC program forconverting irregularly spaced data to grid data by means of the weightedlinear interpolation method (a method to find a local linear trendsurface at each grid point) . The converted grid data are contoured onthe screen of a personal computer using the subroutine *CONTOUR (Shiono et al., 1985a) .
