Mapping Where Norway is Moving

Norway is using Copernicus Sentinel-1 data to detect ground movement across the country.   A collaboration between the  Geological Survey of Norway, the Norwegian Water Resources and Energy Directorate, and the Norwegian Space Centre, data collected by the Interferometric Synthetic Aperture Radar (also known as InSAR) is able to detect ground subsidence and uplift.  Images are collected every six days covering two billion measurement sites in Norway that help to reveal changes in the earth as small as one millimeter a year.   The results are being made available through Norwegian Ground Motion Service – InSAR Norway.

The  InSAR Norway portal is a web mapping interface the provides access to ground movement data.  Use can see areas in Norway experiencing uplift or subsidence.  Clicking on any point on the map brings up a plot for that specific point showing a time series of displacement.  The plot can be downloaded as a .svg format file.  Click no the “view data” button so see the detailed record for that point.  The single data point can be downloaded as a CSV file completed with X,Y coordinate information. There is no visible way to download data for more than one point at a time from the InSAR Norway portal.
