SqueeSAR™ measures ground displacement on roads, railways and surrounding embankments.
Radar imagery can detect ground displacements that could threaten the integrity and safety of road and rail infrastructure (both at grade and elevated). By identifying natural and man-made ground measurement points, SqueeSAR™ maps millimeter displacements along the entire length of road and rail networks, aiding risk assessments and highlighting areas that may require maintenance.
Road, Track and Embankment Stability
SqueeSAR™ displacement maps highlight areas of ground movement over roads and railways, providing engineers with an overview of instabilities that could indicate infrastructure requiring repair.
Ground deformation monitoring produces quantitative and qualitative deformation maps of surrounding embankment instabilities that often precede slope failure, providing a network-wide monitoring tool for assessing areas at elevated risk of landslides and subsidence.
Extensive Network Monitoring
SqueeSAR™ is capable of measuring differential displacements over long stretches of road and track, highlighting areas of subsidence (or uplift) that may require further investigation.
Route Planning
Using a historic archive of satellite imagery, SqueeSAR™ can be used to determine stable areas for potential new routes, assisting also in the planning of network extensions and duplications. Deformation monitoring provides both historic displacement data for route planning and post-construction route stability checks.
Remote Monitoring
As radar imagery is acquired remotely, SqueeSAR™ can provide surface displacement measurements in areas not suitable for ground-based fieldwork. By identifying targets already present on the ground, SqueeSAR™ detects a significantly higher density of ground points than traditional ground-based surveys, such as GPS, leveling and tiltmeters.
