Monitoring Linear Infrastructures with satellite InSAR data
Linear infrastructure projects - such as roads, railways, pipelines, and power lines - can span hundreds of kilometers across varying topographic environments, making them complex assets to monitor.
Understanding ground and slope stability, and areas of possible displacement, is critical throughout the design, construction, and operation phases. InSAR provides synoptic and high-frequency monitoring capability, allowing engineers and project owners to plan operations and maintenance, so as to mitigate risk.
In areas prone to natural hazards, due to the topography of the area, the geologic makeup of the environment or other factors, landslide monitoring is critical. By monitoring road, railway, pipeline, and power line alignments, it is possible to see areas that may be at greater risk of displacement along the designed alignment. InSAR can be used to detect and assess historical and current ground instability, and aid in landslide inventory mapping.
Monitoring Ground Motion
InSAR is an effective tool for monitoring ground surface movement related to landslides, subsidence, or uplift phenomena. InSAR provides precise displacement measurements which are useful throughout all phases of a construction project. It is also a highly cost-effective solution for long-term monitoring programs.
InSAR displacement measurements, obtained through the processing of satellite imagery with TRE Altamira’s SqueeSAR® algorithm, are easily integrated with traditional measurement techniques.
Spatially dense results with millimetric precision
Compared to other measurement techniques, InSAR provides high density displacement measurement point data with millimetric precision.
Non-invasive and scalable technique
Satellite InSAR is completely remote. It is unrivaled in its ability to obtain displacement measurements over large or small areas.
InSAR enhances surveillance and predictive maintenance by providing regular updates on dynamic movement and changes along the alignment and in the surrounding areas.
With frequent satellite image acquisitions and rapid delivery of results, our InSAR monitoring service is easily integrated into operational plans.
Satellite data archives extend back to 1992 and can be processed to provide historical movement trends.
