===== Idea =====

We extract the [[http://www.bafu.admin.ch/luft/luftbelastung/schadstoffkarten/index.html?lang=de|yearly mean values of the air pollution in Switzerland]] from the graphical maps on the BAFU website and present them to a user based on his location: A user should see the cumulative effect of being exposed to pollutants over years. We choose placative statistics, like the amount of particulate matter (PM10, Feinstaub) or the time one spends over the hourly limits of ozone.

The interpolated data for all Switzerland is not available in any other format. Although there is a lot of [[data:health|air pollution measurements downloadable]], they are locally restricted to the measurement stations. The [[http://www.meteotest.ch/en/business_fields/air_quality/immission_mapping/|model behind the interpolation]] is rather complex and also not public.

As a consequence, the project takes an unusual approach: it actually **extracts the data from maps**, i.e. from pictures and re-maps the information to geocodes to offer personalized pollution data.


===== Data =====

databases currently used in the project

  * [[http://www.bafu.admin.ch/luft/luftbelastung/schadstoffkarten/index.html|Yearly mean values on maps]] ([[http://aurora.meteotest.ch/bafu/schadstoffkarten/maps/|All images]], [[https://gist.github.com/f4ff66f0e2cda021aef5|Mapping color hue to pollution value]])
  * [[http://www.cadastre.ch/internet/cadastre/de/home/products/plz/data.html|Geocoded ZIP codes]], File: ''CSV (Excel) LV03''

===== Technology/Services =====

  * http://flask.pocoo.org : the server backend is a simple python app that loads all pictures at startup and quickly calculates local pollution data
  * http://jquery.com : the client is jquery based and uses [[http://jqueryui.com/demos/autocomplete/|jquery.ui.autocomplete]] and [[http://www.highcharts.com/|highcharts]]
  * http://heroku.com : free-for-small-projects webhosting for python web applications that supports virtual environments and continuous updates via git
  * http://github.com : hosts source and data
