InSAR Monitoring
Satellite Deformation Monitoring
InSAR (Interferometric Synthetic Aperture Radar) is a technique for mapping ground deformation using radar images of the Earth’s surface that are collected from orbiting satellites.
Unlike visible or infrared light, radar waves penetrate most weather clouds and are equally effective in darkness. Therefore, with InSAR it is possible to track ground deformation even in bad weather and at night.
InSAR monitoring provides regular updates of ground surface and single asset displacement.
InSAR Monitoring
Providing ground surface motion maps and displacement time series of thousands of measurement points in near real-time.
Wide Area
Regional to national scale displacement information is routinely provided to end-users and decision makers.
Continuous Monitoring
Get actionable information on risky areas through the identification of hotspots, showing a change in the dynamic of motion.
MINING APPLICATION
Measure deformation from millimetres to metres over all mining surfaces, structures and assets without the installation of any in-situ equipment.
Ground motion monitoring with bulletin
Get actionable reports on trends and changes to the ground surface showing movement ranging from millimetres to metres.
Intuitive colour-coded deformation maps highlight areas where changes in trend are occurring with respect to previous situations, providing magnitude and areas of deformation at a glance over the entire mine site.
- Benefit from a quick visualization of deformation trends
- Seamlessly import our maps into your visualization software
- Require tailored report schedules (from every few days to annual)
- Access archives back to 1992 to enhance geotechnical back analysis
Tailings dam stability
Use InSAR to monitor the smallest to the largest dams without the need for on-site visits or installations.
Tailings dam failures are extremely detrimental to mine productivity.
Surface deformation and unattended fractures are common precursors for such costly and harmful events.
- Request frequent updates on the consolidation level and eventual horizontal slips
- Benefit from our remote measurements when access is limited for conventional surveying techniques
Solutions for pit monitoring
Our InSAR mapping service complements in-situ instrumentation, providing an overview of slope movements.
Open pit operations pose many challenges in terms of safety-critical monitoring.
- Investigate slope movements on a weekly basis, utilizing InSAR’s mm-sensitivity, even when precursors are not visible to local alarming facilities
- Easily integrate InSAR data with other geodetic measurements in major monitoring platforms
Underground – Block caving subsidence mapping
Frequent InSAR updates are delivered to surveyors for optimal integration and geotechnical teams for subsurface modelling.
Block caving operations pose serious challenges when dealing with surface displacement monitoring. As heavy subsidence is normal for deep operations, it is essantial to monitor its impact on existing infrastructures to assure service continuity.
- Analyse complex subsidence patterns with InSAR (up to hundreds of measurement points per km2)
- Rely on millimetre-precision vertical displacement measurements
