New options are now available within Data Link's Map View display;

  1. Beta version of new option in Map View to view global bathymetry (Global DEM option). Users can zoom in to display higher resolution bathymetry. Beta version has problem with map display at +/-180°longitude which affects maps for Lau Basin region.
