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.

Landslide Mapping

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 roads, railways, pipelines, 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.
