These data represent a series of mean high water shorelines collected at the Staten Island Unit of Gateway National Recreation Area (GATE), appended into one personal geodatabase. The features have been assembled / collected in support of the Northeast Coastal & Barrier Inventory and Monitoring Network's Ocean Shoreline Position Monitoring Program. The shoreline surveys are collected using a Trimble ProXR, GeoXT, or GeoXH GPS receiver mounted on an ATV, and range in dates from November of 2005 to the most recent updated survey. Depending on the time of year and intended purpose, some surveys contain ocean, inlet and bay shorelines, while some surveys only contain ocean shorelines.
