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.

Abstract: |
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. |
Purpose: |
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. |

Description: |
Marine Cadastre Vessel Traffic (AIS) |
Data Quality
Horizontal Positional Accuracy: |
Compiled to meet 10 meters horizontal accuracy at 95% confidence level |
---|---|
Bias: |
Presence and absence of a record is dependent on the: a) Fixed and unpublished location and height of the receiving antenna relative to the dynamic position, antenna height and wattage of the transmitting vessel, b) Interference of the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 |
Completeness Measure: |
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 |
Completeness Report: |
Records were received from all U.S. Coast Guard NAIS terrestrial receivers. All data records for Alaska, including those collected by NAIS receivers, have been filtered out of our data products, at the request of the Alaska Marine Data Exchange (MXAK), who own a vast majority of the receiving stations across the state of Alaska. |
Conceptual Consistency: |
These data are logically consistent |
Quality Control Procedures Employed: |
The Marine Cadastre project has ended its use of the U.S. Coast Guard's 2018 Authoritative Vessel Identification System (AVIS) database to overwrite vessel attributes in AIS data distributed to the public. Beginning in 2024 the AIS Vessel Identification Database (AVID) is now used to validate and, in some cases, overwrite vessel attributes that are either null or clearly incorrect in their structure or content. These changes have resulted in an improvement to over 10 percent of the total records. The AVID was compiled in late 2023 using over 20 unlicensed and carefully vetted data sources. |

Process Steps
Process Step 1
Description: |
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 |
