You can convert the blanked grid nodes in a GRD file to
any other value a couple different ways:
1.
In Surfer 10, use Grid | Math. In the Grid Math
dialog, click the Add Grids button, select your grid file and click Open. Change the Blank Handling to Remap to and
then enter the value you want for the blanked nodes as the Remap Value. Change
the Output Grid File if you wish and click OK. The new grid is created.
2.
Use the Grid | Filter and choose Linear
Convolution Filters | User Defined Filters | General User-defined (mxn) to fill
a blanked area with a value. Set the
Edge Effects | Blanked Nodes to Fill and the Value to whatever value you want
the blanked nodes to be (ie. 0 or 9999). Change the Output Grid File if you
wish and click OK. The new grid is created.
3.
Use a script. You can download the Blank0.bas
script from our website
(http://www.goldensoftware.com/public/scripts/surfer9/Blank0.bas). If you want to change the blanking value to a
different value than 0, just change the 0 in the script to whatever you want.
