Over 2000 Sentinel-1 Satellite Images Were Used to Create a Map of Land Deformation in the United Kingdom

| |

Over the course of two years, from October 2015 to October 2017, over 2,000 Sentinel-1 images were used to create a map showing ground movement across the United Kingdom.  

The map tracks areas of land subsidence and uplift based on processed data from Sentinel-1’s Synthetic Aperture Radar (SAR).  SAR can be used to detect changes in surface heights with sub-millimeter precision​ in order to map land deformation.

The land deformation map was developed by Geomatic Ventures Limited, a commercial company spun off of the Nottingham Geospatial Institute, University of Nottingham.  Known as the UK Relative Land Motion Map, it covers the United Kingdom with a  spatial resolution of 90 meters.

The web map interface was built with Mango Maps. Using a rainbow classification scheme, the map indicates ares that have subsided (trending red) or uplifted (trending blue) between 2015 and 2017. Users can search for areas by typing in a location or post code or use the pan and zoom tools.  

There are also some areas outlined by rectangles that features areas of interesting subsidence or uplift.
