Sentinel-2, ESA.

Copernicus bretjeneste (page in Norwegian)

Background
Monitoring of glaciers and glacier changes is important for many purposes. The goal of this project is to develope a national service for glaciers in mainland Norway and Svalbard. The Norwegian water resources and energy directorate (NVE) and Norwegian Polar Institute (NPI) are responsible for monitoring glaciers in  Norway and Svalbard, respectively. 

Glacier products
The project will mainly use optical imagery from Sentinel-2, but also Landsat-8 and other sensors when relevant. The glacier products will be made available from NPI and NVE websites (as Web Map Service's and download) and through the CryoClim portal. Data will also be submitted to GLIMS-project (Global Land Ice Measurements from Space: www.glims.org). Glacier Products that will be produced are:

  1. Glacier outline, area and calving front
  2. Glacier surface type and snow line
  3. Ice velocity
  4. Glacier crevasses and surge
  5. Glacier lakes
