    Hi Simba,

    Thank you for contacting Surfer technical support.  To change the coordinates of base map objects you will need to export the map to the desired coordinates.  To do this:

    1. First verify that the map limits have the correct extents.
      1. Click the Map in the Contents window to select it.
      2. Click the Limits tab in the Properties window.
      3. Ensure the xMin is -180, the xMax is 180, the yMin is -90, and the yMax is 90.
    2. Then export the map with the desired coordinates.
      1. Click the Base(vector) layer in the Contents window to select it.
      2. Click File | Export.
      3. In the Export dialog, check Selected objects only, enter a File name, select the desired Save as type, and click Save.
      4. In the Export Options dialog, adjust the File Rectangle X coordinates to be 0 and 360 instead of -180 to 180.

    Please let me know if I can be of any further assistance!
