OPENSTREETMAP ELEMENT VECTORISATION - A TOOL FOR HIGH RESOLUTION DATA INSIGHTS AND ITS USABILITY IN THE LAND-USE AND LAND-COVER DOMAIN

We explored how citizen scientists can help map changes in Arctic landscapes. Using a web tool we created, more than 100 volunteers contributed the approximate center points of particular ground patterns called ice-wedge polygons in aerial images from Alaska and Canada. Our work shows that the data created by volunteers can be used to reconstruct ice-wedge polygon networks and provide valuable insights on the state of frozen ground in the Arctic.
