SqueeSAR™ measures ground subsidence and uplift due to natural causes and anthropogenic activities.

Ground deformation resulting from a variety of causes, known or unknown, can be measured with millimeter accuracy using SqueeSAR™. Imagery acquired from radar satellites can be used to remotely monitor surface displacement over wide areas.

Ground Deformation Monitoring
Remote satellite monitoring of the Earth’s surface highlights the extent of ground deformation occurring over a time period of analysis. By acquiring images over an area of interest, wide areas can be analyzed to produce quantitative displacement data. 

Radar images available back to 1992 are used to create historic subsidence maps, which can provide insight into culpable factors of displacement onset and allow predictions to be made on future behavior.

Displacement Modeling
SqueeSAR™ data can be used to refine surface and subsurface models, providing an improved overview of ground behavior dynamics. Accurate models allow for better management of ground activities (extraction, working, etc.) and assist in minimizing the risk of damage to surface infrastructure.
