f The COSI-Corr tools: Emerging techniques to monitor and quantify ground deformation using high resolution optical imagery and multitemporal LiDAR

COSI-Corr is a suite of algorithms to accurately monitor the Earth's surface using satellite or aerial imagery. We wi" present the fundamental principles of COSI-Corr, which are the key ingredients to achieve sub-pixel registration and sub-pixel measurement accuracy between multi-temporal images. In particular, we demonstrate how ground deformations, involving different types of geomorphological processes, can be recovered using either multi-angle high-resolution optical imagery, or multi-temporal LiDAR acquisitions. We wi" show how the COSI-Corr framework is applied to various types of images to extract 2D, 3D, or even 4D deformation fields.
