ais_global_20112012_grid James T. Potemra ORBCOMM 20130108 Global ship traffic, identifying the number of times a vessel occupied each square kilometer during a one year period: August 2011 through mid-August 2012. The Automatic Identification System (AIS) is an internationally-recognized shipboard broadcast system that communicates information to shore-based stations and other AIS-equipped ships. The U.S. Coast Guard (USCG) has developed rules applicable to both U.S. and foreign vessels that require owners and operators of most commercial vessels to install and use AIS to increase security and safety of maritime transportation. Data were obtained jointly by PacIOOS (J. Potemra), SOEST/ORE of the University of Hawaii (E. Roth), and the Papahanaumokuakea Marine National Monument (PNMN) (D. Graham) through a one-time purchase from ORBCOMM LLC. Due to vendor constraints, release of the raw data is limited. We distribute map imagery only, via Web Map Service (WMS). PacIOOS provides timely, reliable, and accurate ocean information to support a safe, clean, productive ocean and resilient coastal zone in the U.S. Pacific Islands region. 20110801T08:31:08Z 20120817T22:55:24Z Unknown -180.0 179.9 90.0 -90.0 0.0 0.0 Unknown http://pacioos.org/metadata/browse/ais_global_20112012_grid.png Sample image.
