4. South East Strategic Regional Coastal Monitoring Programme – Annual Review Meeting, November 2009 Satellite InSAR Data - Introduction InSAR involves the interferometric processing of the phase component of satellite SAR images of the Earth's surface to quantify surface displacements occurring between image acquisitions. InSAR techniques are capable of remotely detecting millimetres to metres of deformation spanning months, years and even decades, covering specific sites or wide areas (1000s km 2 ) across the world.

7. South East Strategic Regional Coastal Monitoring Programme – Annual Review Meeting, November 2009 motionmap UK is a unique geographic dataset revealing millimetric ground and structure motion trends across the United Kingdom. Derived through processing of hundreds of satellite radar images acquired by European Space Agency satellites between 1992 and 2002. Contains millions of individual motion measurement points, each of which has an associated average annual motion rate. Measurement points correspond to specific features on the ground, typically man-made (e.g. buildings, bridges, walls, piers) but also natural (e.g. rocky outcrops). The dataset identifies motion but does not diagnose cause. Engineering decisions are still required. motionmap UK

23. South East Strategic Regional Coastal Monitoring Programme – Annual Review Meeting, November 2009 Motionmap UK uses archive radar data and is proven to detect motion and movement in the built environment where natural persistent scatters are more prevalent. A key area for current development of the science is involved in the detection of similar motion in the soft engineering environment. To compensate for the potential shortage of natural persistent scatters, artificial scatterers can be deployed in study areas for ongoing monitoring.
