Automatic Identification Systems (AIS) are a navigation safety device that transmits and monitors the location and characteristics of many vessels in U.S. and international waters in real-time. In the U.S. the Coast Guard and industry collect AIS data, which can also be used for a variety of coastal management purposes. NOAA and BOEM have worked jointly to make available these data from the U.S. Coast Guards national network of AIS receivers. The original records were filtered to a one-minute frequency rate, and subset to depict the location and description of vessels broadcasting within the Exclusive Economic Zone.
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.

Compiled to meet 10 meters horizontal accuracy at 95% confidence level
Presence and absence of a record is dependent on the:
a) Fixed and unpublished location and height of the receiving antenna relative to the dynamic position, antenna height and wattage of the transmitting vessel,
b) Interference of the radio frequency transmission between the vessel and the receiving antenna, and the
c) Interference in the collection of the record originating from the vessel
a) Visual analysis of daily record byte count over a year long period
b) Verbal and email communications with U.S. Coast Guard Navigation Center personnel
Records were received from all U.S. Coast Guard NAIS terrestrial receivers
These data are logically consistent

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
Load filtered records to a SQL Server database using MarineCadastre.gov NMEA to SQL Server processing tools
Conduct quality and completeness check using logging results from the filter and loading process, and database record counts
Update the IMO, CallSign, VesselName, Length, Width, VesselType, and Draft from US Coast Guard AVIS
Added or updated the new vessel type code field to each record fragment that was found in the US Coast Guard AVIS
Export records from the SQL Server database to CSV files organized day of the year using MarineCadastre.gov Filter and Export utilities
Modify the format of the date and time values to a UTC string format during export
Modify the format of the IMO vessel number to include the “IMO” prefix during export
Trim white space from string attributes during export
Replaced comma punctuation marks with a semi-colon in the vessel name or call sign field if present to improve CSV formatting during export
Include a header record with descriptive text for each field during export
Write extracted AIS data to an ASCII CSV format file using MarineCadastre.gov Filter and Export utilities
Compress each ASCII CSV file
