In the U.S. the Coast Guard and industry collect AIS data, which can also be used for a variety of coastal planning purposes. NOAA and BOEM have worked jointly to re-task and make available some of the most important records from the U.S. Coast Guard's national network of AIS receivers. Information such as location, time, ship type, length, width, and draft have been extracted from the raw data and prepared as track lines for analyses in desktop GIS software. To support coastal and ocean planning and other activities pursuant to the Energy Policy Act, Coastal Zone Management 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 Vessel Traffic track lines theme MarineCadastre 2011 temporal Gulf of Mexico United States place 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 Maximum scale of intended use is 1:80,000. Completeness Report Spatial and attribute properties are believed to be complete, although attribute information has been simplified. Geometric thresholds from original data are preserved. No tests have been completed for exhaustiveness. Conceptual Consistency These data are believed to be logically consistent. Geometry is topologically clean. 1 Download all 2011 geodatabases for UTM zones 14, 15, and 16 from https://marinecadastre.gov/AIS/default.aspx as well as the AIS Track Builder tool. 2 For all months in Zone 14, 15, and 16 deleted data points from the Broadcast feature class falling outside the United States, Gulf of Mexico region UTM zones 14, 15 and 16. Used Esri's World UTM Grid from ArcGIS online for reference. 3 Create model for each of the UTM zones to run the track builder tool on each of the monthly Broadcast feature classes. Settings used for the tool was to break track lines using "Maximum Time and Distance", maximum time value = 30 and maximum distance value = 1. Also included both the Voyage and Vessel attributes. Ran Model for each UTM zone. 4 CLIP Broadcast points for all months in zone 15 and the months of March and April to smaller quadrants of their respective UTM zone grids. This was to get the tracklines tool to run successfully for the region around New Orleans. 5 Create model to run the track builder tool on each for each of these newly clipped areas. Settings used for the tool was to break track lines using "Maximum Time and Distance", maximum time value = 30 and maximum distance value = 1. Also included both the Voyage and Vessel attributes. 6 MERGE all outputs stemming from step 5 together per month. 7 MERGE of all monthly track line feature classes for each of the UTM zones. Now have 3 feature classes representing total 2011 annual vessel traffic for each UTM Zone 14, 15, and 16. 8 Removal of superfluous fields. 9 Create model to create max draught in meters field for annual feature class, calculate statistics to find the maximum draft value, create new field "maxDraught" in this statistics result intermediate feature class, add values to this new field using field calculator in expression: [max draught statistic] *0.1. This calculation converts the draught values form 1/10th meter units to meter units. Join this field to the annual feature class based on the MMSI field. 10 Repair geometry for each of the annual track line feature classes for each UTM Zone. 11 REPROJECT all three UTM zone's annual tracklines into web mercator. 12 MERGE all three UTM zone's annual track lines into one feature class to create 2011 annual Gulf of Mexico track lines feature class. 13 Repair geometry for the merged regional file. 14 Add spatial index. 2014-02-01T00:00:00 Source Contribution: 2011 AIS at 1 Minute Intervals for UTM Zone 14, 15, and 16.
