2015 Map of Nantucket OE S

About this map

The Atlantic Ocean dominates this offshore survey south of Nantucket, capturing the open waters and the maritime boundary of Nantucket County. This specific area, mapped in 2015, represents a nearly purely aquatic quadrant, with the only terrestrial presence appearing at the extreme northeastern corner. Here, a small segment of land is bisected by Mattapoisett Rd, a local connector on the island's southern fringe. Because this map focuses on the waters of the Atlantic Ocean, it serves as a precise record of the shoreline and maritime jurisdictional limits at a time when digital mapping data for elevation was not yet meeting accuracy requirements for contouring. It is a vital document for those studying the coastal orientation and administrative reach of Massachusetts into the sea.
