Road Traffic Noise Exposure Areas for Departmental Road 740 Near Niort

A 2019 dataset from the Bureau de Recherches Géologiques et Minières (BRGM) mapping noise exposure along the departmental road 740 from Aiffres to Niort in Deux-Sèvres, France. It contains isophone curves representing the Lden noise indicator, calculated in 5 dB(A) steps from 55 dB(A) over a full day, as required by the European Directive on Strategic Noise Maps. The data was collected in accordance with French environmental law implementing the directive.

Use Cases
