From Vienna to the world: launch of citizen science campaign to measure #trees and map carbon
On 23 June 2025, #IIASA will launch the global #CitizenScience “Tree-Quest” campaign at the Living Planet Symposium in #Vienna, inviting people from all over the world to take part using the free #GeoQuest app. As part of the Citizens for #Copernicus project, IIASA researchers will also lead hands-on workshops with schoolchildren at the symposium, teaching them how to use the app and collect ground data that will help scientists map the #carbon stored in trees with #satellite data more accurately.
