Remote SensingThree-dimensional coseismic surface deformation fields are important for quantifying the geometric and kinematic characteristics of earthquake rupture faults. However, traditional geodetic techniques are constrained by intrinsic limitations: Interferometric synthetic aperture radar (InSAR) can only extract far-field deformation fields owing to ...

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information SciencesAbstract. Currently, two types of satellite laser altimetry systems are in operation: the full waveform linear system and the single-photon-counting system, which exhibit significant differences in both data format and processing methodologies. It remains uncertain which satellite laser altimetry technology offers greater advantages in assisting stereo
