This API provides geographic data on groundwater bodies within the Aix-Marseille-Provence Metropolitan area in France, published by Métropole Aix-Marseille-Provence. The dataset is harvested from the regional environmental authority (DREAL) and delivered as a geographic layer using the RGF93/Lambert 93 spatial reference system (EPSG:2154). It is useful for environmental and hydrogeological analysis, water resource management, and spatial planning at the local level within the metropolitan territory.Données moissonnées sur le site de la DREAL. La couche provient du fichier géographique avec le système de référence spatiale RGF93/Lambert 93 (EPSG:2154).
