The interoperable INSPIRE Mapping Service (WMS) Health and Safety provides an overview of the isophonic maps of road traffic noise in Brandenburg according to Directive 2002/49/EC (Environmental Noise Directive). This requires the EU member states to assess and combat environmental noise. As a result, strategic noise maps had to be drawn up by June 30, 2007 as part of the first stage. These are to be revised and updated every five years. The data in question includes the 4th round of EU noise mapping (2022), in which new, harmonized calculation rules are applied. All municipalities in the state of Brandenburg with roads > 3 million vehicles/year were examined. As required by Section 2 of the 34th BImSchV, the two noise indices LDEN and LNight are displayed on duty. According to the INSPIRE data specification Human Health And Safety (D2.8.III.5_v3.0), the contents of the map are INSPIRE-compliant. The WMS contains the following layers: - HH.HealthDeterminantMeasure: contains isophones of road traffic noise exposure for the entire day (lden) and night (lnight) - HH.HealthDeterminantMeasure.MRoad.lden: contains isophones of road traffic noise exposure for the entire day (lden) - HH .HealthDeterminantMeasure.MRoad.lnight: contains isophones of road traffic noise exposure for the night (lnight)
