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. To support ocean planning activities pursuant to the Executive Order Regarding the Ocean Policy to Advance the Economic, Security, and Environmental Interests of the United States, the Energy Policy Act, the Rivers and Harbors Act, and the Coastal Zone Management Act.

Parameters for these data were 1 nautical mile and 30 minutes. Conceptual Consistency These data are logically consistent 1. Filter the raw NMEA data to a one-minute sample rate and select a subset of fields using Marine Cadastre NMEA to SQL Server processing tools 2. Load filtered records to an SQL Server 2025 database using MarineCadastre.gov NMEA to SQL Server processing tools 3. Conduct quality and completeness check using logging results from the filter and loading process 4. Update the VesselType, Length, Width, and Draft from United States Coast Guard AVIS where original AIS values are missing 5. Add a new vessel type code to each record fragment that originated from the United States Coast Guard AVIS 6. Develop track line features directly from the SQL Server database using a customize version of the Marine Cadastre Track Builder 3.1 (64-bit version) for each month of broadcast records and for each ocean basin, using a filter setting of 30 minutes and 1 mile 7. Add field for vessel type group and populate based on the vessel type code to vessel group mapping described in attribute metadata 8. Add field for track line duration, and calculate the time in minutes between the start and end time for each track feature 9. Perform visual quality and consistency checks, and remove vessel tracks that are clearly invalid (on land) or beyond the ocean basin 10. REPAIR GEOMETRY to correct features with null geometry, self intersections, and other errors 2026-03-01T00:00:00 Source Contribution: Daily compressed log files containing original AIS messages in NMEA format for the months of January through December for the United States U.S. Coast Guard Navigation Center 2026-01-01 publication
