AIS Vessel Tracks 2018

Published by Office for Coastal Management | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: July 14, 2026 at 09:57 PM | Dataset Last Updated: June 23, 2020 at 12:00 AM
A vessel track shows the location and characteristics of commercial and recreational boats as a sequence of positions transmitted by an Automatic Identification System (AIS). AIS signals are susceptible to interference and this can result in a gap within a vessel track. The distribution, type, and frequency of vessel tracks are a useful aid to understanding the risk of conflicting uses within a certain geographic area. The vessel track positions in this data set are collected and recorded from land-based antennas as part of a national network operated by the U.S. Coast Guard.
