Process_Description: Merge all other polygons.

Process_Step:

Process_Description:

Edit/ Adjust polygon if neccessary based on WV2 imagery. USGS Topo maps hydrlines (DRGs) were used a secondary reference.

Process_Step:

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.
