• Kunghit & Moresby Island Shorelines: Precision configuration of the coastlines for both islands, identifying elevations, drying reefs, and essential aids to navigation.

• Critical Bathymetry: Shows the nature of the sea bottom and precise water depths, essential for vessels transitioning between the high-energy Pacific and the more sheltered eastern sounds.
