Ground Stability
Interferometric Synthetic Aperture Radar (InSAR) can generate maps of surface deformation or elevation, using satellite radar data. Depending on the situation, InSAR can detect and monitor centimetre to millimetre scale deformation over wide areas, right down to monitoring of local areas and structures. Applications include monitoring of urban structures, infrastructure, tunnelling, subsidence, landslides, resource extraction and geological phenomena.
In addition to a wide variety of commercial projects, they have a significant involvement with national and European bodies such as British National Space Centre, British Geological Survey and the European Space Agency (ESA). Major projects include Terrafirma, which provides a ground motion hazard information service distributed throughout Europe via national geological surveys and institutions, and the Pipemon project which studied remote sensing technology for routing and monitoring of pipelines. Their PSI study of London in collaboration with the Environment Agency received national press coverage, showing ongoing subsidence in east London.

Famous quotes containing the words ground and/or stability:
“Some people are like ants. Give them a warm day and a piece of ground and they start digging. There the similarity ends. Ants keep on digging. Most people don’t. They establish contact with the soil, absorb so much vernal vigor that they can’t stay in one place, and desert the fork or spade to see how the rhubarb is coming and whether the asparagus is yet in sight.”
—Hal Borland (1900–1978)
“Every quotation contributes something to the stability or enlargement of the language.”
—Samuel Johnson (1709–1784)
