Mark the Ice Wedge Polygons‘ Center

Difficulty Level 3 (Special Agent)

Are you ready for the next level? This task helps us in finding the exact position of the ice-wedge polygons. From this data we can then obtain important information about the condition of the permafrost. At the bottom left you can select the mapping tools. Your task: Mark the (approximate) centre of the polygon. Your marker can also be moved or deleted afterwards, if needed.
