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.
Topography & Mapping
24 March 2017
With the pair of Sentinel-2 satellites now in orbit, users are looking ahead to mapping global land cover at 10 m resolution.
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.
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.
22 June 2016
The twin Sentinel-1 satellites have - for the first time - combined to show their capability for revealing even small deformations in Earth's surface.
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.
08 June 2015
With frequent observations from the year-old Sentinel-1A radar satellite scientists are improving the remote sensing technique to map ground deformation, opening new doors for earthquake and volcano monitoring.
29 April 2015
Results from a recent field campaign, which was organised to help investigate the potential of a new Earth observation mission concept, have provided a unique 3D glimpse of the peaks and troughs under the Mittelbergferner glacier in the Austrian Alps.
23 March 2015
Scientists are making advances in the use of satellite radar data - such as those from the Sentinel-1 mission - to monitor Earth's changing surface.
24 October 2014
The first satellite-based service for extensive and uninterrupted monitoring and mapping of land stability has won the top prize in the European Earth-monitoring competition.
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.
