      Process_Description: Smooth polygon first with algorithm (80 m smoothing tolerance, PAEK), then in some areas by hand.
    Process_Step:
      Process_Description: Clip with Guam polygon -> disregard overlapping area. Clean up polygons by removing small slivers left from different outlines used for Guam shoreline.
