Transverse limit of the sea

Geographic information layer including the Transverse limit of the sea - mainland France, French Guiana, Martinique and Guadeloupe. This layer must be considered as an initial version to be validated locally by the competent services. Shom actively seeks out any information which could complete and improve the precision of this layer. The streams and rivers listed correspond to those mentioned in the applicable regulations and/or by a competent Government service. An inventory of existing legal and geographic information was drawn up prior to production in the form of an enquiry targeting services during the second half of 2014. The source legal text and a summary of digital conversion processes is available for each boundary proposed.Updated july 2018

Statement: Geographic information is digitized from the indications (textual descriptions) contained in the legal texts. As far as possible, digitization was systematically carried out using the most precise geographical reference system (Ortho Littoral V2). At each limit is associated a summary sheet summarizing the production methods of the data and indicating the degree of precision (type of positioning: known precisely (uncertainty less than 50 m), approximate (uncertainty between 50m and 200m), doubtful (uncertainty > greater than 200 m) impossible).
