Spatial datasets from the hydrographic office and air traffic department are available through the Download and View Service of the Finnish Transport and Communications Agency.
In the file download service you can view and download data using a map-based interface. Most of the data available in the service is open. The terms of use for the downloaded data are shown in the download basket when downloading the data.
You can select the datasets and area you would like to view or download. Once you have made the selection, the service sends you an email with a download link. The datasets are delivered as shape (.shp) -files.

The Download and View Service also contains some sets of background data that are not available for download (e.g. S-57 ENC and the Traficom WMTS view service).
