3. Once the updated grid file is created, double click on the contour map to open the Map: Contours Properties dialog.

5. Select the updated grid file and click Open.

To update a post or classed post map with new data, follow these steps:

You cannot update base or wireframe maps in Surfer 8. If you wish to update one of these map types, you must delete the map and recreate it. If the map is part of an overlay, you must break apart the overlay before you can delete the map.
