OGC API Processes interface service

Via the OGC API Processes interface service, you can download all datasets without a user interface directly for your own use. The use of the interface service requires more technical skills than the use of the user interface service. The service is suitable, for instance, for use where there is a need to search spatial datasets repeatedly or in large amounts. The search parameters enable the downloading of the dataset with coordinates as a rectangular selection (Bounding Box) or a polygon selection, one map sheet at a time or covering the whole of Finland. The interface service is open but requires an API key.

Description and technical information of the OGC API Processes interface service

Updating service

You can update downloaded data by using the Open data file updating service. The service is an ATOM feed, i.e. a standardised web feed in XML format. With the Updating service, you can search for all files sorted by product version that have been updated after a certain date. The feed you receive as a reply contains direct links to download updated files. You can download only those files that have been updated. 

You can use either a standard browser or other feed reading software to receive the feed (The NLS does not offer user support for such software).

You can order the identification key required to use the Updating service into your e-mail inbox. The use of the service is free of charge.

Directory user interface

Through the directory user interface, the NLS's downloadable topographic data and cadastral index map data products are available as files. Through the directory user interface, you can copy files from directory folders. Through the directory user interface, you can also download older versions of orthophoto data, laser scanning data, municipal division data and geographic names. Through the directory user interface, it is possible to download more files in one go, if you have access to a batch programme.

The use of the directory user interface requires authentication with username and password. You can order usernames at There is a one-time payment for setting up usernames. See the price list here. When you order the username, tell us which products you need.
