AIS Decoder is an AIS-data forwarding utility (developed by Neal Arundale) which can be used if you own an AIS receiver with a serial output and you wish to share your AIS-data with MarineTraffic.
AIS Decoder accepts incoming AIS-data collected by your AIS Receiver, decodes it and presents the decoded data in a form suitable for display and analysis by a chart-plotter utility (for example, the MarineTraffic Live Map) or by a database (for example, the MarineTraffic central database).
