This dataset, reflecting the 2002 situation, was produced by the Agence de l'Eau Seine Normandie (AESN) in partnership with the Institut Paris Region. It results from digitizing the surface hydrography of the Île-de-France region based on IGN topographic maps at 1:25,000 scale. The dataset delineates elementary watersheds and covers the entire territory of the Île-de-France region, providing a basis for hydrological and land-use analysis at a fine spatial resolution across the region.[Situation 2002] L'AESN (Agence de l'Eau Seine Normandie), en partenariat avec l'Institut Paris Region, a fait numériser l'hydrographie de surface de la Région Île-de-France à partir des cartes IGN au 1/25.000.
