Have all Ice Wedge Polygons been mapped?

Difficulty Level 2 (Junior Agent)

Artificial Intelligence (AI) supports us when mapping permafrost structures. But even the AI algorithms make mistakes, which is why we need your help in finding these errors. Compare the marked polygons with the background imagery. Click once if all polygons have been detected. In case you find new, unmarked polygons, click twice. You can also choose “unsure”. The arrows will lead you to the next set of images and your work will be saved.
