Table of Government & Open-Source AIS Data Sources
In addition to the sources listed below, it may be possible to obtain data sets from the responsible agency of a country whose water's are of interest. This will likely entail an application and justification process.
Raw NMEA AIS data sharing centre; only contains current data of ships in range and geographic statistics organized by receiving station. Users must regularly query the system for current data and store it on their own.
Requires contribution of data feed in order to gain access to the community of sources
