The maritime boundaries data is available under the open license (Étalab 2017 license). This digital data is the only one binding on all the sea users under Article 16 of Order No 2016-1687 of 8 December 2016 relating to maritime spaces under French sovereignty or jurisdiction.

The portal is the reference platform for geographical maritime and coastal information pursuant to the INSPIRE Directive. The maritime boundaries are presented here, but the portal also allows you to search, view and access geotagged data from Shom.
