SYNOPSIS

Satellite radar imagery has been acquiring over Malaysia for many years. By processing such imagery with an advanced ‘Interferometric Synthetic Aperture Radar’ (InSAR) processing chain, it is possible to map current and past ground displacements to millimetre accuracy. In a typical InSAR analysis, millions of synthetic ground measurement points can be typically detected, each of which has an accompanying time-series of recent ground movement behaviour, indicating areas of stability, instability, displacement magnitude, velocity and acceleration. Such maps, updated on a regular basis, provide a wide-area and detailed understanding of slope instabilities and long-term ground settlement / movement. InSAR offers an accurate, cost-effective and repeatable mapping solution for slope and ground instability mapping, as well as long-term monitoring of infrastructure. Furthermore, the technique is complimentary with in-situ observations and is completely remote, meaning no need for ground instrumentation or equipment maintenance. The discussion will cover an introduction to InSAR, where InSAR fits in with traditional monitoring and applications and case studies for civil engineering & slope monitoring.
