This dataset from Rennes Métropole provides noise level contour layers (isophones) showing threshold exceedances from various noise sources—road, rail, and industrial—measured over a 24-hour period (Lden) and at night (Ln). The rail network contours were updated in 2023 to account for the commissioning of the new high-speed rail line (LGV) and related infrastructure changes. The data supports noise pollution assessment and urban planning within the Rennes Métropole area.Couche d'isophones indiquant les dépassements de seuil de différentes sources de bruit (routier, ferré et industriel) sur 24h (Lden) et la nuit (Ln). Les courbes d'isophones pour le réseau ferré ont été mises à jour en 2023 pour tenir compte de la mise en production de la nouvelle LGV et de la li...
