Monitoring Earth’s Surface Dynamics with Optical Imagery by Sebastien Leprince, PhD Candidate, EE, Caltech

Despite the increasing availability of high quality optical satellite images, continuous monitoring of Earth's surface changes is still of limited use due to technical limitations. To overcome these limitations, we propose a processing chain to accurately orthorectify and coregister sets of pushbroom images, which, associated with a precise correlation technique, allows for the measurement of ground deformations with accuracy on the order of 1/20 of the pixel size. Applications related to earthquake ground deformations, ice flow, and landslides, are presented.
