Overview

Data showing the locations and characteristics of vessels in U.S. and international waters are obtained from the U.S. Coast Guard’s Automatic Identification System (AIS), an onboard navigation safety device. These data are used by the ocean planning community for traffic analysis, ecological studies, and other offshore, location-based research. These data are part of a larger collection of authoritative and trusted ocean planning geospatial data on Marine Cadastre.
