Copernicus Sentinel-1 data fuel Norwegian ground motion service
10 January 2019
Launched in late November 2018 by the Geological Survey of Norway (NGU), the Norwegian Water Resources and Energy Directorate (NVE) and the Norwegian Space Centre (NSC), InSAR Norway is a service that aims to monitor and measure ground movements on a national scale, using Copernicus Sentinel-1 data.
The ground beneath us is constantly changing. Seasonal changes in temperature and soil moisture can cause ground expansion and contraction. Buildings, bridges, roads and railways shift and settle due to the soft ground underneath them. Mountainsides can slide slowly and silently downwards for hundreds or thousands of years, before collapsing catastrophically. Like the rising global temperatures, many of these movements are infinitesimal—only millimetres or centimetres each year. Nevertheless, the cumulative effect of these movements can be disastrous.
