An InSAR HPC system and the generated national deformation map of China

An InSAR high-performance computing (HPC) system developed at Chinese Academy of Surveying and Mapping is reported. Time series Sentinel-1 SAR images covering the whole territory of China acquired between 2021 and April of 2022 was processed by this HPC system, and a national deformation map was generated. Main deformation phenomena across the country and their causes are summarized.
