Grid Files

Contour maps, color relief maps, shaded relief maps, vector maps, watershed maps, 3D surfaces, and 3D wireframes all require grids for their creation in Surfer. A grid is a regular, rectangular array of values. The Home | Grid Data | Grid Data command provides you with several methods for generating a Surfer .GRD grid file from your XYZ data. In addition to the grid files that Surfer creates, it can also read many common grid file formats directly. A grid with all NoData nodes cannot be saved.
