This API provides strategic noise mapping data on industrial noise exposure across the Aix-Marseille-Provence metropolitan area, expressed using the Lden indicator (day-evening-night noise level) for 24-hour periods, as part of Type A noise maps. The data was produced by Impédance Ingénierie on behalf of the Métropole Aix-Marseille-Provence. Associated map symbology is available as an attachment in QGIS format. The dataset is useful for assessing industrial noise pollution and exposed zones at the local level within the metropolitan area.Cartographie de Bruit Stratégique Donnée produite par Impédance ingénierie pour le compte de la métropole Aix-Marseille Provence La symbologie associée à la carte du bruit est disponible dans la partie pièce jointe, au format QGIS Bruit industriel selon l'indicateur Lden pour les cartes de type A...
