Geotechnical

摘要

Queen's University Belfast together with the British Geological Survey (BGS) and the Geological Survey of Northern Ireland (GSNI) have just embarked on an exciting new research study to illustrate how satellite radar interferometry (InSAR) techniques can be used to remotely assess small ground movements in geotechnical or structural infrastructure, with millimetre precision. The satellite radar data is available from 1992 onwards and can be used to either assess historical ground movements or alternatively monitor current movements or ground subsidence.
