Advanced Sensor Technologies in Geospatial Sciences and Engineering 2020.

Advanced sensor technologies in geospatial sciences and engineering research have contributed to (1) geographic mapping and (2) understanding the geological, ecological, hydrological, and environmental characteristics of Earth surfaces. W. Zhu et al. in their paper entitled "Pre- and Postcollapse Ground Deformation Revealed by SAR Interferometry: A Case Study of Foshan (China) Ground Collapse" investigated the ground deformation in the vicinity of the collapsed sinkhole in the Foshan collapse event using multitemporal SAR interferometry. W. Zhu et al. in their paper entitled "Spatiotemporal Characterization of Land Subsidence in Guandu (China) Revealed by Multisensor InSAR Observations" investigated the time-series two-dimensional ground deformation in Guandu using the multisensor InSAR observation.
