Information layer containing the SAR Zones (Search and Rescue). This layer contains a description of the French search and rescue (SAR) areas and the location of the associated Maritime Rescue Coordination Center (MRCC). it covers the areas of responsibility of France. The layer was produced by the Shom pursuant to the Circular Circular of the International Maritime Organization (IMO No. SAR.8 / Circ.4 of 1 December 2012).

The combined error grid of the SIO V31 gravity anomaly model (D. T. Sandwell, H. Harper, B. Tozer et al., Gravity field recovery from geodetic altimeter missions, Advances in Space Research, https://doi.org/10.1016/j.asr.2019.09.011) is computed with a method described in a paper submitted to Earth and Space Science (AGU). The model’s extension is North Atlantic.

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.

Title V of Volume IX of rural and sea fisheries laws defines the measures related to Overseas territories. Articles R951-14 and R953-5 in particular define for specific Overseas territories a limit located at 100 nautical miles from the in force baselines. Inside this limit, fisheries are limited to the ships registered in the ports of those Overseas territories, except dispensation allowed by State. Those restrictions are not applied to ships registered in the European Union which are traditionally fishing in those waters, as long as they do not exceed the fisheries effort which is traditionally applied.

The regulatory part of Volume IX of rural and sea fisheries laws is defined by the decree No 2014-1608 of 26 December 2014. In particular, Article D922-16 of the appendix to the decree defines a limit related to fisheries located at 3 nautical miles from the low waterline of the continent and islands and islets which are always dry. In the particular case of Mayotte Island, in compliance with Article 61 of the prefectural decree No 2018-681 of 30 July 2018 which regulates the exercise of sea fisheries at Mayotte department, this limits is located at 3 nautical miles from the in force baselines.

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. 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 and downloaded on the French national portal of maritime limits (https://maritimelimits.gouv.fr).

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.

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).

French Ministry of Agriculture and Food / DRASSM - Shom<br /> The product "Limits related to fishery uses" contains the limits related to fishery uses as defined in the French or European legislations. Those limits are managed by the Directorate for Sea Fisheries and Aquaculture (DPMA) of the Ministry of Agriculture and Food. <br /> Those limits are divided into three categories : <br /> - the inner limit of the coastal waters (6 nautical miles) ; <br /> - the 3-nautical-mile limit ; <br /> - the limit of fisheries for overseas territories (100 nautical miles).<br /><br /> The product "Limits related to fishery uses" 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.<br /> 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).

Compilation of marine gravity surveys acquired in the Northeast Atlantic by Shom between 2001 and 2016. These surveys were compiled to perform a quantification of the error of the gravity anomaly models derived from satellite altimetry. This dataset represents more than 22,000 measurement points distributed in 9 ascii survey files sampled at 1 kilometer. The file’s format is as follows: longitude latitude Gravity_anomaly error line_label.
