Surfer supports ESRI grid files, so if you wish to use these grids in Surfer, there is no need to convert them. If you do need to convert an ESRI grid file to a Surfer grid file for another reason, follow these steps:
- Click Grids | Edit | Convert.
- In the Open Grid dialog, select your ESRI grid file and click Open.
- In the Save Grid As dialog, give the new file a name, choose to save it in Surfer 7 Binary Grid format, and click Save. The grid is converted.
