The database is composed of 216 self-contained File Geodatabases (FGDB). Each FGDB represents one month of data for a single UTM zone. The UTM zones represented cover the entire United States and include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 14, 15, 16, 17, 18, 19, and 20. Each FGDB consists of one feature class, four tables, and two relationship classes. The Broadcast point feature class contains the position reports, which have been pre-filtered to a one-minute time step. The Voyage table contains elements of the static data reports that are updated for each ship voyage. The Vessel table contains elements of the static data reports that are specific to a particular vessel. The BaseStations table lists the base stations collecting data for a particular month/UTM zone. The AttributeUnits table contains a list of units for each of the attribute fields in the Broadcast, Voyage, and Vessel tables. The BroadcastHasVessel relationship class relates the broadcast points to the vessel table records. The BroadcastHasVoyage relationship class relates the broadcast points to the voyage table records. To support coastal planning and other activities pursuant to the Coastal Zone Management Act, Energy Policy Act, Magnuson-Stevens Fishery Conservation and Management Act, National Environmental Policy Act, Rivers and Harbors Act and the Submerged Lands Act. completed NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information pointOfContact NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information custodian notPlanned EARTH SCIENCE > HUMAN DIMENSIONS > ENVIRONMENTAL GOVERNANCE/MANAGEMENT theme Global Change Master Directory (GCMD) Science Keywords 23.3 CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA OCEAN > ATLANTIC OCEAN > NORTH ATLANTIC OCEAN > GULF OF AMERICA place Global Change Master Directory (GCMD) Location Keywords 23.3 AIS Automatic Identification System Nautical charting coastal and marine spatial planning ocean planning position report static data report vessel voyage theme Atlantic Ocean Bering Sea Great Lakes Gulf of Mexico Pacific Ocean UTM Zone 1 UTM Zone 10 UTM Zone 11 UTM Zone 14 UTM Zone 15 UTM Zone 16 UTM Zone 17 UTM Zone 18 UTM Zone 19 UTM Zone 2 UTM Zone 20 UTM Zone 3 UTM Zone 4 UTM Zone 5 UTM Zone 6 UTM Zone 7 UTM Zone 8 UTM Zone 9 United States place sea level stratum DOC/NOAA/NOS/OCM > Office of Coastal Management, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

Horizontal Positional Accuracy Positional accuracy reflects the specifications and methods of the original data producer and has not been modified for the generation of this product. Completeness Report Points were filtered to a one-minute time step before publishing the data. Vessel identification data was altered prior to distribution by encoding the MMSI numbers and removing the vessel name, IMO, and call sign information. Conceptual Consistency Point data. No topology between points. The data was divided spatially by UTM zone and aggregated temporally to monthly datasets using AISParser. The data was then converted to FGDB using the AIS data model created for this project and a custom script which implements AISParser and ArcObjects. 2012-01-01T00:00:00 Source Contribution: Data received for the entire United States in a total of 6668 files of AIS messages for the months of January through December. Data were received in 6576 hourly files for January through September and in 92 daily files for October through December. Hourly files were missing for January 1st to January 4th, with the exception of the hourly timestamp 01-04-16. | Type of Source Media: disc 2012 NAIS Database US Coast Guard 2012-01-01 2012-12-31
