This API provides data from Strategic Noise Mapping produced by Impédance ingénierie on behalf of Aix-Marseille-Provence Metropole. It covers industrial noise according to the Lden indicator for type C maps across the metropolitan area, presenting results of acoustic modelling calculations. The dataset identifies zones where regulatory limit values for industrial noise are exceeded over a 24-hour period. It is published and maintained by Métropole Aix-Marseille-Provence, offering geographic detail on noise exposure at the local level for environmental and urban planning purposes.Cartographie de Bruit Stratégique Donnée produite par Impédance ingénierie pour le compte de la métropole Aix-Marseille Provence Bruit industriel selon l'indicateur Lden pour les cartes de type C sur la Métropole Aix-Marseille Provence.
