This dataset provides the linear features of the "Graus" (coastal inlets) within the Blue Corridor component of the Regional Ecological Coherence Scheme (SRCE) for the former Languedoc-Roussillon region. The layer, named "Grau_R91", was supplied by the regional environment authority DREAL LR in January 2015. Documentation is limited, as this layer is specific to the former Languedoc-Roussillon region rather than the wider merged Occitanie region. It supports mapping of ecological connectivity related to coastal water bodies within the regional biodiversity framework.Linéaires des Graus de la Trame Bleue du Schéma Régional de Cohérence Ecologique en Languedoc-Rousillon. Couche fournie en janvier 2015 par la DREAL LR sous le nom "Grau_R91". Peu d'information disponible, cette couche étant spécifique à l'ancienne Région Languedoc-Roussillon par rapport aux autr...
