54204 Data Set Published / External 55360 Automatic Identification System (AIS) Project Completed 2018-10-31 Vessels traveling in U.S. coastal and inland waters frequently use Automatic Identification Systems (AIS) for navigation safety. The U.S. Coast Guard collects AIS records using shore-side antennas. These records have been filtered and converted from a series of points to a set of track lines for each vessel. Vessels can have one or more tracks of any length, and can be separated by gaps due to intermittent loss of the AIS signal. Tracks will not necessarily start or stop at a well defined port, or when a vessel is not in motion. Vessel tracks are an efficient and spatially unbiased indicator of vessel traffic. 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.

AIS Vessel Tracks 2016: Filtering of AIS messages in NMEA format to an 1 minute interval and conversion of message to track line features by vessel type and ocean basin. 1 1. Filter the raw NMEA data to a one-minute sample rate and select a subset of fields using MarineCadastre.gov NMEA to SQL Server processing tools 2. Load filtered records to an SQL Server 2017 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 IMO, CallSign, VesselName, Length, Width, VesselType, 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 MarineCadastre.gov 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. Added field for vessel type group and populated based on the vessel type code to vessel group mapping described in attribute metadata 8. Added field for track line duration, and calculated the time in minutes between the start and end time for each track feature 9. Performed visual quality and consistency checks, and removed vessel tracks that were clearly invalid (on land) or beyond the ocean basin 10.
