RAW AIS stream possible??

[Brian Bach Mortensen]

Hi Everyone

I am currently using raw AIS data from a number of other servers where AIVDM/BVDM messages are exchanged realtime through a normal socket. I am wondering if this would be possible to gain access to through digitraffic or any other way (for Finnish waterways of course).

Thanks in advance for any replies!

Hi,

Unfortunately, due to technical and security reasons we are unable to provide raw ais data. For example location of fishing vessels is a business secret. Converting current data back to raw format would require significant effort.

HI There

Thanks for the quick support, we will use the regular services as described on swagger. 

Not sure I understand the concern about the fishing vessels? Seems like they are very public on several big global marine sites, so I hope the fishing competition is not aware of those web sites :D

Is any other ship data filtered out of the AIS data available on swagger?

Kind regards

Hello,

The open data AIS stream from the Finnish Transport Agency follows the regulation set by EU and by some Finnish officials.

The fishing vessel filter is based on the opinion of the European Data Protection Supervisor (52012XX0210(01), see http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:52012XX0210(01) 

The Supervisor states that the location of the Fishing vessels may be personal data, not a trade secret like Ville wrote earlier.

We are also filtering all messages from B-class transmitters based on the opinion of the Office of the Data Protection Ombudsman in Finland. According to their statement, information from B-class transmitters can be considered personal data and should not be shared. This statement is not available in English.

More information about our policies is available in the (Finnish) document https://www.liikennevirasto.fi/documents/20473/38174/AIS_tietopalvelut_p%C3%A4ivitys_esittely_LiTijory_160418.pdf/8c360bb6-e4a6-4eb8-994d-a664706d655a

It includes some tables where the column "Julkaistaan" means "to be published and the subcolumns "Kyllä" and "Ei" mean "Yes" and "No".

Finally, regarding the raw (IEC/NMEA) data our current implementation does not support this kind of operation, but this may change in the future.

I'm aware of the current development of the big global marine sites and the fact that all this information is publicly available over VHF.  Hopefully open data fron the Finnish Transport Agency can add some value to other, more complete AIS sources!
