Difficulty: Level 1 (Beginners).
Here you can see aerial imagery of arctic landscapes, e.g. taken with a drone by students in Aklavik. By clicking on a tile (multiple times), you can decide whether or not the characteristic ice-wedge polygons can be detected. If you are unsure, you can also chose the option “maybe”. The arrows will lead you to the next picture sequence and your work will be saved. Thank you for your contribution!
