Dataset description

The water leash includes: — the leash of the highest waters (limit of land never covered by the sea), the continuity of which is ensured on the whole of the BDCarthage. In the case of islands, it shall be seized only if it delimits an area of ​​#x27; an area greater than or equal to 1 hectare; — the leash of the lowest waters (limit of the land still submerged), where it is more than 100 meters from the leash of the highest waters (otherwise it is not seized) and outside the estuaries (where an arbitrary line closing the estuary is seized in place of the leash of the lowest water). In the case of islands emerging only at low tide, it shall be seized only if it delimits an area of > #x27; an area greater than or equal to 4 hectares. A leash section is located by geometric arcs, corresponding to the cut-offs by attributes managed by the IGN: nature. The change in value of an attribute only results in the creation of a leash section if the new value remains constant over a length of at least 1 km. __Origin__ Update based on the information transmitted by l'IGN __Partner organisations__ ASH __Links annexes__ * [see scenario d' geographical exchange of the hydrographic reference](http://www.sandre.eaufrance.fr/urn.php?urn=urn:sandre:scenario-d-echanges-geographique:eth:FRA:::ressource:1:) * [see the interactive dictionary on Sandre website](http://www.sandre.eaufrance.fr/?urn=urn:sandre:dictionnaire:ETH::entite:LaisseEaux:ressource:2002-1:::html) * [see Dictionary & Hydrographic Reference (ETH)"](http://www.sandre.eaufrance.fr/?urn=urn:sandre:notice:dictionnaire::theme:ETH:ressource:2002-1:::html) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/0ddf35a234bb2c43888b99ba33f022f80216b1da)
