Digiroad data consists of the centre line geometry of the transport network, traffic-related attribute data and other transport system objects.
The centre line geometry covers the vehicle-accessible roads, ferry and cable ferry connections for cars, railways and separate pedestrian and cycle routes. Traffic-related attribute data include the attribute data of traffic elements as well as the restrictions, limits and other features of the road and street network. Other transport system objects include, for example, services.
The structure is depicted more detailed in the description of data objects found here.
Digiroad data is available as open data. Therefore it is free to use for everyone. When using the data, follow the Creative Commons BY 4.0 license specifications.
Digiroad data can be downloaded from FTA's View and Download service. The data can be downloaded either as a nation-wide package or as smaller packages based on the Finnish region division. Digiroad data consists of ESRI shapefiles, each of which includes the geometry and attribute data of one data object. Digiroad data is available in two different formats (R and K).
|Digiroad R||Digiroad K|
|Digiroad R contains dynamically segmented attribute data on reference chains. It is delivered in ESRI shape format.||
Digiroad K is a delivery format in which traffic elements have been cut into parts containing uniform attribute data. Delivered in ESRI shape format, Digiroad K is suited for use with, for example, MapInfo products.
Both versions are available in ETRS-TM35FIN coordinate system.
Some of the data objects are published also in a beta WFS interface by the Finnish Transport Agency. New data objects are continuously added in the WFS interface. If you use the interface, please note that the data format might be due to changes.

Digiroad data updates available in TN-ITS API
Changes occurred in Digiroad data is available in TN-ITS API. Datasets are updated once a day and they are released here:
Datasets are created using the OpenLR library. For now, the material contains also the minor changes in geometry, not only the actual changes in attributes. At the moment the API includes changes concerning speed limits and maximum allowed limits (7 categories).
