How can I resample my Surfer grid to be a higher resolution?

There are two ways to resample a grid to be higher resolution:

  • Resample the grid with the Mosaic command
    1. Click Grids | Resize | Mosaic.
    2. In the Open Grid(s) dialog, choose your grid file and click Open.
    3. In the Grid Mosaic dialog, increase the # of Nodes or decrease the Spacing in the Output Grid Geometry section.
    4. If desired, change the Resample Method.
    5. Give your Output Grid a name and click OK. The new grid is created.

  • Smooth the grid using the Spline Smooth command
    1. Click Grids | Edit | Spline Smooth.
    2. In the Spline Smooth dialog, choose your grid-based map from the Input Grid dropdown list or click the Browse button to select your grid file.
    3. In the Method section, choose to Insert Nodes if you just wish to add additional nodes but don't want to reinterpolate the grid.
    4. In the Number Nodes to Insert section, choose how many nodes to insert between each set of adjacent nodes in the x (rows) and y (cols) directions.
    5. Give your Output Grid a name and click OK. The new grid is created.
