Note that does not have access to LIVE AIS data feeds, or more recent data than what is provided on this webpage. Please see the FAQ page for more information about AIS data. These AIS data can be accessed through the AccessAIS tool or through the data download interface. Information such as location, time, vessel type, speed, length, beam, and draft have been extracted from the raw data and prepared for analyses in desktop GIS software. Coast Guard’s national network of AIS receivers. Coast Guard Navigation Center have worked jointly to repurpose and make available some of the most important records from the U.S. The Bureau of Ocean Energy Management (BOEM), the National Oceanic and Atmospheric Administration (NOAA), and the U.S. Coast Guard through an onboard navigation safety device that transmits and monitors the location and characteristics of vessels in U.S. Note: VTS Louisville is only operational during high water.Vessel traffic data, or Automatic Identification System (AIS) data, are collected by the U.S. If you're looking for a quick reference guide, please see our 'VTS Radio Procedures'. The Coast Guard operates 12 Vessel Traffic Centers (VTC): Prince William Sound, Puget Sound, Valdez, Seattle, San Francisco, Los Angeles/Long Beach, Houston-Galveston, Berwick Bay, Louisville, Saint Mary's River, Port Arthur, Tampa, and New York.ĬLICK HERE to visit the VTS Locations page with a clickable map that will display each VTS operating area description and links to user manuals & homepages (if available). The addition of a network of radars, AIS, and close circuit television cameras for surveillance and computer-assisted tracking, similar to that used in air traffic control, allows the VTS to play a more significant role in marine traffic management, thereby decreasing vessel congestion, critical encounter situations, and the probability of a marine casualty resulting in environmental damage. Transiting vessels make position reports to a vessel traffic center by radiotelephone and are in turn provided with accurate, complete, and timely navigational safety information. VHF-FM communications network forms the basis of most major services. They are also designed to expedite ship movements, increase transportation system efficiency, and improve all-weather operating capability. They encompass a wide range of techniques and capabilities aimed at preventing vessel collisions, rammings, and groundings in the harbor, harbor approach and inland waterway phase of navigation. Non-surveilled systems consist of one or more reporting points at which ships are required to report their identity, course, speed, and other data to the monitoring authority. radar, AIS and closed circuit television sites), which output their signals to a central location where operators monitor and manage vessel traffic movement. Surveilled systems consist of one or more land-based sensors (i.e. There are two main types of VTS, surveilled and non-surveilled. The purpose of a Vessel Traffic Service (VTS) is to provide active monitoring and navigational advice for vessels in particularly confined and busy waterways.
