Dataset produced by Impédance Ingénierie on behalf of the Aix-Marseille-Provence Metropolitan Authority, part of a strategic noise mapping study. It provides the 2020 locations of acoustic noise barriers installed across the metropolitan territory, intended to support noise pollution assessment and urban planning. The data is published as an open API by the Aix-Marseille-Provence metropolitan area and covers a local geographic scope within France.Cartographie de Bruit Stratégique Donnée produite par Impédance ingénierie pour le compte de la métropole Aix-Marseille Provence Localisation en 2020 des écrans anti-bruit sur le territoire de la métropole Aix-Marseille-Provence.
