The Worldwide Dissonance Pollution Map

The OSM Global Noise Pollution Map uses OpenStreetMap information to map the levels of racket pollution across the world. At the middle of the OSM Global Noise Pollution Map is the real clever but uncomplicated reckon of assigning racket pollution levels based on OpenStreetMap tags.

Map features inwards OpenStreetMap are assigned a tag to depict what has been mapped. These tags tin rank notice too live on assigned a value. For illustration all roads are tagged every bit a 'highway' but are too assigned a value such every bit 'motorway', 'secondary' or 'residential;.

The OSM Global Noise Pollution Map run these tags too values to assign a racket pollution marking based on full general assumptions. For illustration highway, trunk, main too secondary roads are deemed to live on noisier than normal street or service roads. The OSM Global Noise Pollution Map too assumes that railways too retail & industrial zones volition too accept a marking of racket pollution associated amongst them.

Such a blanket approach plainly has its limits. Looking at the map merely about where I alive inwards London I'd grip amongst the bulk of the racket levels but at that topographic point are 1 or ii buildings which definitely aren't every bit noisy every bit the map suggests.

However, quibbles aside, this is a groovy reckon too I'm certain that it tin rank notice live on refined further. For illustration at that topographic point are a lot of dissimilar types of retail outlet tags inwards OpenStreetMap, then at that topographic point is perhaps room to refine the levels of racket pollution assigned to each type of store too store on the global map.
