ENVI4ALL

Targeted air quality information based on open data and crowd-sourcing

ENVI4ALL is a mobile application that offers information on the current, forecast, and historical air pollution levels, making use of open data on air quality and user-generated information.

It uses air pollution measurements for the calculation of the Air Quality Index (AQI): an index for reporting daily air quality based on the associated health effects people may experience from breathing polluted air. The forecasts provided by the app are produced by DRAXIS’ advanced forecasting algorithms and models. Furthermore, users are able to state their feeling (perception) on air quality and see other people’s feelings. This information is used for estimating air pollution in areas where no open data are available, or for improving the accuracy of the information provided by open data. ENVI4ALL combines all this information to provide users with personalised alerts for poor air quality and practical advice in organising their activities.
