Portvision
PortVision is a web service that allows maritime shipping and transportation companies to track commercial vessel traffic, including real-time vessel locations and up to five years of historical data.
==History==
The PortVision vessel-tracking service was created in 2006 by Airsis, a company based in San Diego that was formed in 2004 from the merger of Abaris Technologies, founded by Dean Rosenberg, and Applied Digital Security Inc., founded by Jim Drewett. The PortVision service uses the Automatic Identification System (AIS), a technology and communication protocol that has been adopted by the International Maritime Organization as an international standard for ship-to-ship, ship-to-shore and shore-to-ship communication of navigation information. Using AIS, the PortVision service provides oil companies, marine terminal operators, fleet owners/operators and other maritime users with information about commercial vessel activities within ports and inland waterways. The PortVision service was developed after TOTAL Petrochemical and three other refineries in the Beaumont-Port Arthur, Texas, area asked Airsis to develop a more elaborate, ship-tracking version of an on-line mapping system that the company had designed for the Port of Houston. Current users include international ports like the Port of New Orleans as well as large inland ports in the US.
