Pollution Relief, Switzerland



This project is based on maps of the annual mean values of pollution in Switzerland, concentrating on fine particles (PM10). Using these maps, and the software Processing, i’ve created a 3D topography of Switzerland based not on the relief topography of plateaus, foothills and mountains, but on the variations of the values of pollution (PM10) measured every year. Thus, the higher the pollution is, the greater the relief will be.

A reversal of the Swiss terrain



The result is a reversal of the Swiss terrain, cities: Ticino, Plateau and Valley Rhône become mountainous; while the Grisons Alps become flat. The final outcome takes the form of an interactive map of the years 2003, 2007 and 2010 alongside a 3D physical print of each of these years pollution topography. The physical printing of these maps allows intangible pollution to acquire a certain materiality.
