| From
mapping the areal coverage and magnitude of ground motions following
cataclysmic earthquakes, to measuring discrete subsidence displacements
over several years, satellite Radar Interferometry (InSAR) has
a wide variety of uses in ground movement surveying applications.
For several years now, NPA have been routinely detecting and
mapping to sub-centimetric levels many types of large-area ground
motions
using InSAR techniques. As well as heading major research projects
in this field for the European Space Agency and the European
Commission, NPA is contracted to undertake this work, not only
in the UK but throughout the world, on behalf of local government
agencies, risk management companies, commercial organisations
such as mining companies, and geological survey institutions.
