- 6. Common problem Silos ofinformation Novisibility Nocommondataaccess Services not in place Toocomplex Not alwayscompliant
- 7. Noise as environmental pollution Effects Hearing loss Cardiological effects Stress Annoyance Emitters Airports, cars, industrial sites, neighborhood, etc. Subjective Cannot be modeled or calculated

- 10. OpenStreetMap Collaborative and open platform Inventoryofoutdoorobjects Roads, Crossings, Buildings, POIs Simple datamodel Points, lines, tags Updates throughchangesets Access through APIs
- 11. Approach Publishcontent on commonplatform OpenStreetMap Assign tag toexistingornew OSM object Tags formeasuredproperty Visualizethroughspecificrenderers
- 12. Implementation Noise community Web Processing Service OSM API Publication Service 12

Example OSM API query select http://api.openstreetmap.org/api/0.6/map?bbox=7.573375599999999,51.9294798,7.5753756,51.9314798 OSM API query update <?xml version="1.0" encoding="UTF-8" ?> <osm generator="OpenStreetMap server" version="0.6"> <node changeset="8712284" id="273968126" lat="51.9310517" lon="7.5706349" timestamp="2011-07-12T14:25:37Z" uid="478890" user="A_user" version="3" visible="true"> <tag k="noise_day" v="50.1" /> </node> </osm>
