French Groundwater Level Monitoring Stations (Hub'Eau, ADES Piezometry)

hubeau/groundwater-stations

Lists French groundwater level monitoring stations (piezometers) from the national ADES portal: BSS code, commune and INSEE code, department, coordinates, altitude, investigation depth, first and last measurement date and number of measurements. Choose how many stations to return (1 to 100) and optionally filter by commune INSEE code. This lists the stations only, not the water-level measurements. Data from Hub'Eau, producers OFB / BRGM / SCHAPI-Vigicrues, Licence Ouverte Etalab; served by Eden Engine; not an official Hub'Eau product.
