The Ferry Terminals map shows the origin and departure sites for ferries. The Ferry Routes map shows the approximate alignment of routes as determined through GPS and Automatic Identification System (AIS) data, as well existing government datasets from the Census Bureau, the U.S. Geological Survey, the National Oceanic and Atmospheric Association, and the U.S. Army Corps of Engineers. Users can click on any route for information about its operator, where it begins/ends, the time of year it runs, and more.
