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. This record represents the metadata for each of these vessel types: Cargo, Fishing, Passenger, Pleasure Craft and Sailing, Tanker, and Tug and Towing.
Knowledge graph centered on 2017 Vessel Transit Counts by Type with 4 nodes and 6 connections. Top connected: vessel traffic, coastal zone management, AIS vessel traffic monitoring.
