The data of thematic maps are also available via open data (WMS/WFS services).

FTIA's old WMS/WFS services will be taken down after 31.1.2023. The old services will no longer be in use. Information about FTIA's new WMS/WFS services can be found on the Open API -page.

FTIA has published a QGIS-plugin, which enables search-features in terms of road- ands street adresses. More information regarding the plugin can be found via FTIA's GitHub. ​​​​

Noise data from roads and railways in year 2022 has been published via our open data: open API & Download- and viewing service

Public road data from Tievelho has been published via our open data: open API & Download- and viewing service

Historical road network data (since 2009) has been published as open data via the AVA-service.


​​​​The distribution for open traffic measurement data This is an external link (Liikenteen automaattiset mittaustiedot, LAM) has moved to Fintraffic. The data is available from its new service in the same formats as before via Digitraffic (link).

The service for open data distribution (Aineiston välitysalusta - AVA) is being updated. The address of the new service is:

We'll inform here when data is moved to the new service. "The old AVA-service" will be in use until end of January 2022.


​​​​The distribution for open traffic measurement data  (Liikenteen automaattiset mittaustiedot, LAM) will be moved to Fintraffic in January 2022 . The data will available from its new service in the same formats as before. More information on exact dates and URL for the new service will be published on this page and Fintraffic's Digitraffic-service as soon as possible.

The Excel user interface for Viitekehysmuunnin (location reference converter) moves to
The new address is already available for use. The old address was taken off use officially 1st of December 2021 and concretely 14th of January 2022.
The functionality of the interface will remain the same in the new address, with some exceptions:
•    You can use a column named Tunniste (identifier) in the input file if you wish to add an identifier for the row.
•    You can add a column named Väylän luonne or Tie (lead type or road number) to an input file with the type XY if you wish to target the search to a given lead type or a road.
Please note that if you use a Tie-column here then one row in the input file can produce two rows into the output file (one for each track 1 and 2 if the search result is located on one of these neighboring tracks). Hence it is advisable to use Tunniste if you search with XY + Tie.
•    The Katuosoite-column is split into Katunimi- and Katunumero-columns in the output file.
The functionality of the Excel user interface will be developed further in the coming spring. If you have any questions about the interface, please contact us at [email protected].

There will be changes in FTIA’s GIS services from late 2021 to early 2022.
