Minimize Overview
Interferometry is one of the key techniques in the creation of digital elevation models for the mapping of large areas and in the monitoring of elevation change in areas of land subsidence or uplift.

Satellites confirm San Francisco tower is sinking

25 November 2016

The Sentinel-1 satellites have shown that the Millennium Tower skyscraper in the centre of San Francisco is sinking by a few centimetres a year. Studying the city is helping scientists to improve the monitoring of urban ground movements, particularly for subsidence hotspots in Europe.

Early warning from space of homes on the slide

23 November 2016

It was a literal property crash: multiple homes in the Cármenes del Mar resort on the south coast of Spain were engulfed in a landslide, leaving families homeless. But satellite archives offer early warning of such events - and now more accessible than ever before thanks to a new cloud computing platform.

Mapping that sinking feeling

01 June 2016

For a low-lying, densely populated country like the Netherlands, monitoring subsidence is critical. Until recently, tiny displacements in the ground beneath our feet couldn't be mapped nationally but, thanks to the Sentinel-1 mission, this is now possible.

Sentinel-1 poised to monitor motion

26 August 2014

Although it was only launched a few months ago and is still being commissioned, the new Sentinel-1A radar satellite has already shown that it can be used to generate 3D models of Earth's surface and will be able to closely monitor land and ice surface deformation.
