Can you give me some examples of the SHP files exported from Surfer?

There are many various options to choose from when exporting to a SHP file from Surfer, and a few examples are attached to this article. The Surfer shapefile export creates the SHP, DBF, and SHX files. Note that images are not exported to SHP files. This includes image base maps, color relief maps, shaded relief maps, and 3D surface maps.

You can use File | Export to export to a SHP file using the default settings (see attached FileExport3.zip). You have the option to write the points and areas as lines to the same file or write them to separate files. You also have the option to render text and marker symbols as polygons. The Z values for the contour lines (if a contour layer is exported) is saved to the DBF file for each polyline object.

If you want to export a contour map and retain the Z value of contours in the DBF file, select the contour map and use the Map Tools | Layer Tools | Export Contours command in Surfer. You have the option to export to a 3D SHP file (see attached ExportContours3D.zip) and 2D SHP file (see attached ExportContours2D.zip).

The 2D SHP exports a shape 2D polyline type where each vertex along the line comprises an X and Y coordinate. The Z coordinate for each vertex is stored in the associated DBF file.

The 3D SHP exports a shape polyline Z type where each vertex along the line comprises an X, Y, and Z coordinate. The Z coordinate for each vertex is stored in the associated DBF file.
