Dataset Direct Download Service (WFS): Type A map of areas exposed to noise (Day-Soirée-Nnight) for the Côte-d’Or rail network

These maps also referred to as “type A maps” represent for the year 2017 in the form of isophone curves, the areas exposed to more than 55 dB(A) according to the Lden indicator, with a step of 5 in 5 dB(A). They concern the Côte-d’Or rail network. Lden: sound level indicator means Level Day-Evening-Night. It corresponds to an equivalent 24-hour sound level in which evening and night noise levels are increased by 5 and 10 dB(A), respectively, to reflect greater discomfort during these periods. These aggregated data are published for use in mapping purposes. It is advisable to load the detail data for more accurate use.
