In the Law of the Sea, a straight baseline is composed by a loxodrome connecting two points of the low-water line or low-tide elevations if there is a lighthouse or similar permanent infrastructure on them. The conditions to draw such lines are defined in Article 7 of UNCLOS. The straight baselines are part of the baselines of a coastal State below which the internal waters are defined. Those straight baselines, in addition with the normal baseline, compose the inner limit of the territorial sea and are the basis of the computations of the outer limits of other maritime spaces defined by UNCLOS. They are also composed of the closure line for bays and rivers in compliance with Aricles 9 and 10 of UNCLOS. The objects of the theme "Straight baselines" result from Shom computations and are published by decree of the French Republic.

In compliance with Article 33 of UNCLOS, the outer limit of the contiguous zone is located at 24 nautical miles from the baselines. The objects of the theme "Outer limit of the contiguous zone" result from Shom computations and are compliant with Article 10 of the French Order No 2016-1687 of 8 December 2016.
-
In compliance with Article 3 of UNCLOS, the outer limit of the territorial sea is located at 12 nautical miles from the baselines. It corresponds to the inner limit of the contiguous and exclusive economic zones. The objects of the theme "Outer limit of the territorial sea" result from Shom computations and are published by decree of the French Republic. Some of those limits are note published by decree yet.
-
The theme "Agreed maritime boundaries" contains the delineation limits between maritime spaces under sovereignty or jurisdiction of France et neighbouring States which are established by ratification of a boundary agreement or by a decision of an arbitral tribunal or an international legal body entitled to deal with cases relating to the Law of the Sea.

French Ministry of Culture / DRASSM – Shom The product "Limit of preventive archeology licence fee" contains the limits for the preventive archeology licence fee (1 nautical mile) as defined in the French Heritage Code. This limit is managed by the Department of Underwater Archeological Research (DRASSM) of the Ministry of Culture. This limit, defined by the Heritage Code at 1 nautical mile from the low-water line, permits to delineate the areas where the licence fee for preventive archeology at sea is applied. In Mainland France in the Gironde estuary, the limit for the preventive archeology licence fee is stopped by the crosswise limit of the sea as defined by the decree of 26 August 1857. In French Guiana, the limit for the preventive archeology licence fee is stopped in Maroni and Oyapock rivers by the crosswise limits of the sea respectively defined the order of 30 January 1991 and the order No 863 of 26 May 1986, until meeting the land boundary which delineates the rivers with the neighbouring States. The product "Limit of preventive archeology licence fee" is to use in addition to the digital product “Maritime Limits and Boundaries” of Shom (French: “Délimitations maritimes”) which represents the limits of the French maritime spaces of sovereignty or jurisdiction through the World. The product “Maritime Limits and Boundaries” (French: “Délimitations maritimes”) can be viewed on data.shom.fr (Maritime boundaries Category) and downloaded on the French national portal of maritime limits (https://maritimelimits.gouv.fr).

The "Sovereignty and jurisdiction maritime spaces of France" product contains the areas of sovereignty and jurisdiction maritime spaces of France all around the world.<br /><br /> It is constituted of 2D areas objects split into four categories :<br /> - the territorial sea (from baselines to a distance of 12 nautical miles or to maritime boundaries with neighbouring countries);<br /> - the contiguous zone (from 12 nautical miles to 24 nautical miles from the baselines or to maritime boundaries with neighbouring countries);<br /> - the exclusive economic zone (EEZ) (from 12 nautical miles to 200 nautical miles from the baselines or to maritime boundaries with neighbouring countries);<br /> - the continental shelf over the 200 nautical miles limit (from 200 nautical miles from the baselines to the limits recommended by the Commission on the Limits of the Continental Shelf (CLCS) or to the maritime boundaries with neighbouring countries).<br /> Internal waters, which constitute a space of sovereignty beyond the baselines, are not included in the "Sovereignty and jurisdiction maritime spaces of France" product.<br /> The "Sovereignty and jurisdiction maritime spaces of France" product may not be considered as an enforceable right. Only the “Maritime limits and boundaries” product, that can be displayed and interrogated on the website data.shom.fr (maritime boundaries category) and also downloaded on the French national portal of maritime limits (https://maritimelimits.gouv.fr), may be considered so.<br /><br /> December 2022 version.

The product “Maritime limits and boundaries” (French: “Délimitations maritimes”) gathers all the elements used for the definition of the maritime spaces under the French sovereignty or jurisdiction through the world. Those spaces are defined by the Ordonnance n° 2016-1687 of 8 December 2016 relating to maritime spaces under sovereignty or jurisdiction of the French Republic. This ordonnance is the transcription in the French legislation of the United Nations Convention on the Law of the Sea (UNCLOS) which was signed in Montego Bay (Jamaica) on 10 December 1982 end ratified by France on 11 April 1996. These elements of maritime limits and boundaries come from the limits computed by Shom on the basis of International Law, from the international agreements relating to maritime boundary and the technical conventions ratified between France and other States, from the decisions of international juridical bodies, from the recommendations of the Commission of the Limits of the Continental Shelf (UNO) or from unilateral claims from France in the absence of agreement. The elements are divided into seven themes: 1- Straight baselines 2- Outer limits of the territorial sea (12 nautical miles) 3- Outer limits of the contiguous zone (24 nautical miles) 4- Outer limits of the exclusive economic zone (200 nautical miles) 5- Maritime boundaries established by a bilateral agreement or decided by an international juridical body 6- Maritime boundaries unilaterally claimed by France in the absence of agreement 7- Outer limit of the continental shelf beyond 200 nautical miles December 2022 version

In the Law of the Sea, the continental shelf located beyond 200 nautical miles affects the seabed and its subsoil on which the coastal State exerts sovereign rights for purposes of exploration and exploitation of its natural ressources. In those areas, the wealth generated by the exploitation of the natural ressources are shared via the International Seabed Authority between the States which have signed UNCLOS (in particular with the developping States or the ones which do not have access to the sea). The outer limit of the continental shelf beyond 200 nautical miles is determined in compliance with the criterias of Article 76 of UNCLOS and notably by the examination of a submission deposited by the Coastal State to the Commission for the Limits of the Continental Shelf (CLCS). the outer limit of the French continental shelf beyond 200 nautical miles is the final result of the national program EXTRAPLAC after the adoption of recommandations by CLCS, the delineation of the attributed areas with neighbouring States if necessary and the publication by decree. The theme "Outer limit of the continental shelf beyond 200 nautical miles" gathers the limits of the extended continental shelf which has been recommended by CLCS and published by a decree of the French Republic.

In compliance with Article 57 of UNCLOS, the outer limit of the exclusive economic zone (EEZ) is located at 24 nautical miles from the baselines. This limit distinguishes the EEZ from the High Sea. Beyond this limit, an extension of the continental shelf is possible subject to the criterias of Article 76 of UNCLOS. The objects of the theme "Outer limit of the exclusive economic zone" result from Shom computations and are compliant with Article 10 of the French Order No 2016-1687 of 8 December 2016. They are published by decree of the French Republic.
