Glacier lakes in mainland Norway have been mapped from Sentinel-2 satellite imagery from 2018. In total, more than 400 lakes were mapped and categorized based on the nature of damming and contact with the ice interface. Glacier dammed lakes and jøkulhlaup events were identified. The report also discusses advantages, and limitations in mapping of glacier lakes with Sentinel-2 imagery.
Glacier surface velocities:
Surface velocity of glaciers in mainland Norway were mapped from optical Sentinel-2 imagery over the period 2015-2018. All glaciers in mainland Norway were categorized based on the potential to extract surface velocity measurements using Sentinel-2 and feature tracking. In total, results were acquired over 91 glacier units, whereof 37 in northern Norway and 54 in southern Norway. This report also discusses advantages and challenges of using Sentinel-2 for mapping surface velocity of glaciers in mainland Norway.
Copernicus Glacier Service Norway
The work is a contribution to the project Copernicus Glacier Service Norway, a Cooperation between the Norwegian water resources and energy directorate (NVE), the Norwegian Polar Insitute and the Department of Geosciences, University of Oslo. The service will mainly use data from the Sentinel-2 satellite in the Copernicus-programme. The Project is partly funded by the Norwegian Space Centre through Copernicus.
