Surfer (by Golden Software)

oExporting to Surfer before creating the contour generates only the .dat file, so you can use your own gridding options (e.g. nearest neighbor, kriging etc.).

oExporting to Surfer after creating the contour generates the .dat, .grd (nearest neighbor interpolation), and the plotted contour. You can review the contour, then go back to the .dat file and change the gridding options, if desired.


Note: A Plus Graphics License is required for Surfer.
