Airborne radar maps of ground movement (UAVSAR)

UAVSAR_INSAR_INTERFEROGRAM_GRD
deformation NASA ASF Level 1 active
In plain English

What it measures. Radar maps of ground movement made by comparing two aircraft radar passes over the same area (an interferogram), projected onto the ground. The abstract is brief, so further detail isn't stated.

How it's made. Produced from repeat flights of the UAVSAR radar aboard a NASA G-III aircraft, with two passes combined using interferometry and then projected onto the ground.

How & where you'd use it. Useful for detecting subtle surface shifts such as those from earthquakes, landslides or subsidence, though specifics aren't given in the brief description.
