Germany’s ground movements mapped using Copernicus Sentinel-1

Changes in land-surface occur over time due to several natural and mand-made factors such as groundwater extraction, mining, natural consolidation of sediments, urbanisation etc. It is vital to measure these changes since these can cause damage to buildings, roads, bridges and other infrastructure over time.

Germany’s ground movements mapped using Copernicus Sentinel-1

For the first time, with the help of the Copernicus Sentinel-1 radar mission, shifts in the land surface across the whole of Germany have been mapped. Changes in land-surface occur over time due to several natural and mand-made factors such as groundwater extraction, mining, natural consolidation of sediments, urbanisation etc. It is vital to measure these changes since these can cause damage to buildings, roads, bridges and other infrastructure over time.

As reported by Spacedaily, Copernicus Sentinel-1 is a two-satellite mission that delivers radar images which can map ground movement and help identify changes as small as a few millimetres. Germany’s Federal Institute for Geosciences and Natural Resources (BGR) is using the mission’s data to generate the country’s first nationwide map of ground deformation. This map shows how the land surface across Germany has shifted in millimetres between 2014 and 2018. Such efforts can significantly aid in more effective urban planning.
