On the map, geographic shapes have been simplified to optimize the display of the layer. The entire layer, without simplifying geographic shapes, is available in SHAPE format in the Export/Alternative Exports tab.
The symbology associated with the noise map is available in the attachment part, in QGIS format.
Road noise according to indicator Ln for type A maps on the Aix-Marseille Provence Metropolis.
Calculation results of acoustic modelling.
