Water level data are available through an API (Application Programming Interface), which makes it possible to extract and integrate data with your own systems.
Documentation and user guide for the API are available at http://api.sehavniva.no/tideapi_en.html.
The API is open for everybody and does not require registration, but the Norwegian Mapping Authority Hydrographic Service must be credited, since we are licensee of the data.
The use of the data are licensed through Creative Commons Attribution 4.0 international (CC BY 4.0).
Please send us feedback at firstname.lastname@example.org, especially if you use the data to create new services or apps.
