Force elevation refresh (Right mouse click)
Select this option to force the elevation to be refreshed for this waypoint. Even if the elevation is in the local database, GSAK will check the external servers for a more current elevation and use that instead of the local value. As this process can be slow and place demands on the external servers, you can only do one waypoint at a time. This is the only way to refresh the elevation from the external server. Also see the option "Database=>update elevation"
