insar.sk provides satellite-based InSAR monitoring of infrastructure and areas prone to hazards such as landslides. InSAR can monitor hundreds of structures simultaneously through clouds and at night with frequent satellite passes. It helps identify areas needing inspection and complements terrestrial monitoring with higher spatial resolution. InSAR of an area in Slovakia detected landslides subsiding up to 3 cm per year across three villages. insar.sk monitors structures worldwide for deformation and provides timely awareness of hazards.
