PV-WAVE GTGRID® gives PV-WAVE users additional interpolation and extrapolation power by providing access to a library of gridding routines prepared by Geophysical Techniques (GT), Inc.

The GTGRID Library is a structured collection of FORTRAN routines for solving surface estimation (gridding) problems. It is especially valuable for PV-WAVE users in such areas as:

The core function of PV‑WAVE GTGRID, the GTGRID function, accepts 3D data from PV-WAVE in the form of x, y, and z vectors. The result from the GTGRID function is a 2D array containing the gridded z values on a uniform x-y grid.

Other functions in the PV‑WAVE GTGRID suite allow you to manipulate and subset gridded data, and work with surface data.

The PV‑WAVE GTGRID functions are described in Reference.
