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 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. This dataset represents annual vessel transit counts
summarized at a 100 m by 100 m geographic area. A single transit is counted each time a vessel track passes
through, starts, or stops within a 100 m grid cell.
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.

Evaluation method description:
a) The geographic extent of these data include the conterminous United States, Hawaii, U.S. Virgin Islands
and Puerto Rico.
b) Presence, absence, and contiguity of a track is dependent on the distance and temporal filters applied
in the track building algorithm. Parameters for these data were one nautical mile and 30 minutes.
c) This is an aggregate data product derived from input files that were segmented generally by ocean
basin. A gap can be seen along the seam line of the input files. The gap distance should never exceed
the distance a vessel has traveled between two consecutive position records.
