The interoperable INSPIRE data set provides an overview of the isophone maps in the Potsdam metropolitan area in accordance with 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 3rd stage of the EU noise mapping (2017). The isophone maps are provided for 1. road traffic noise, 2. industrial and commercial noise and 3. rail traffic noise (tram only). A schema transformation took place in the INSPIRE target schema health and safety. The data set is the basis of the interoperable INSPIRE display (WMS) and download services (WFS): Strategic noise maps for the Potsdam metropolitan area 2017 - Interoperable INSPIRE View-Service (WMS-HH-LAERMKPDM2017) Strategic noise maps for the Potsdam metropolitan area 2017 - Interoperable INSPIRE download -Service (WFS-HH-LAERMKPDM2017)
