中国大陆1970-2018部分InSAR资料目录

InSAR数据主要从各个不同项目组（课题组）收集而得，对于垂直形变显著大于水平形变（如沉降区）、其它观测资料明显不足时，可利用InSAR视线向形变作为重要补充。理论上GNSS给出的高精度水平形变、精密水准给出的高精度垂直形变和InSAR给出的高空间分辨率的视线向形变可通过融合计算起到互补作用，是本项目欲做的一种尝试，但因收集到的资料在空间和时间上的分布都过于零散，相互在时间上和空间上相互匹配不足，没有给出很好的融合结果，但作为数据汇编共享，在积累数据足够多时，将会体现出越来越重要的价值与作用。

InSAR data are primarily collected from multiple research groups. For regions where vertical deformation is significantly greater than horizontal deformation (such as subsidence areas) and other observational data are severely insufficient, InSAR-derived line-of-sight (LOS) deformation can serve as an important supplementary data source. Theoretically, fusing the high-precision horizontal deformation data from GNSS, high-precision vertical deformation data from precise leveling, and high-spatial-resolution line-of-sight deformation data from InSAR can achieve mutual complementarity, which is a targeted attempt of this research project. However, due to the overly scattered spatial and temporal distribution of the collected data and insufficient spatial-temporal matching between different datasets, no satisfactory fusion results have been achieved so far. Nevertheless, as a data compilation and sharing resource, it will exhibit increasingly important value and functions as the accumulated data volume increases.
