Principles for open data

Open data is an important factor in all development, planning and purchases that FTIA does.  Open data and Open API's are a key factor when renewing old and designing new information systems like the Law for Traffic Services in Finland (2017/320) obligates. FTIA aims to open its data collections for public use in machine readable formats via Application Programming Interfaces (APIs).

All public data can be published according to the principles of open knowledge. Before the data is opened, Finnish Transport Infrastructure Agency confirms that there are no legal obstacles for the publication.

The openness of data means that the data can be used


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- and streed adresses. More information regarding the plugin can be found via FTIA's GitHub.
