APIExecutable4/7Query nowOpen workbench Subscribe🇫🇷France

This dataset defines a 5-kilometre buffer zone measured inland from the coastline of the Brittany region in France. It is derived from the "Limite Terre-Mer" (land-sea boundary) reference data produced by SHOM, the French Hydrographic and Oceanographic Service. The dataset is published via the Brittany regional open-data portal and provides a geospatial layer useful for coastal planning, environmental analysis, and regulatory purposes requiring delineation of areas near the shoreline. Access is free and does not require authentication.Bande des 5km créée à partir du trait de côte sur la région Bretagne Basée sur la donnée "Limite Terre-Mer du SHOM"
