Two Sherbrookers Among the Finalists of NASA Competition, an app created by two Sherbrookers and a Montrealer, ranked in the top 20 of the People’s Choice Award for the International Space Apps Challenge, a competition organized by NASA.

The team, consisting of developer Nicolas Lupien, computer science student Alex Provencher, and imaging programmer Lucie Bélanger, designed a tool to determine air quality… by photographing tree leaves!

The principle is simple: using a smartphone, you take a picture of a tree leaf, and then tweet it to @foligram. The app uses the picture’s colours and irregularities to calculate the surface of the leaf affected by ozone air pollution and then redirects you to a link containing the leaf’s data.

As a result, the team collects data from all over the world to refine its air quality analyses. is the winner of the Montreal final, which was held at the Planetarium in mid-April.
