Announcing the Winners of Esri’s New Global Content Challenge

Esri’s new Global Content Challenge contest, engaging students all over the world, is proud to announce the winners!

The contest was open from August to November and Esri was happy to receive ~550 registrations from students in nearly 60 countries, with 70 actual submissions. A distinguished international panel of judges chose projects that best exemplified the spirit of the contest: unleashing the power of Esri’s Living Atlas of the World content.
