Grids Tab Commands

There are many ways to manipulate grid files in Surfer. The Grids tab contains commands used to assign the NoData value, convert, create, extract, filter, mosaic, slice, smooth, and transform grid files. In addition, volume calculations, variogram generation, calculus operations, cross section creation, and residual calculations can be performed using the commands under the Grids tab.

 

Data
