In this paper, we discussed the method of data processing for geological data obtained by sampling along the survey lines. Because density of sampling is not isotropic for the types of data, it is difficult to convert them to grid data which represent the original geological structure reasonably. In order to resolve the problem, the method of the weighted least square interpolation in the FORTRAN subroutine PELTO (Shiono, 1982) were modified so that the weight has directivity. Moreover, we presented a method for mapping the reliability of the converted grid data in order to evaluate the calculated results.
