中国大陆1970-2018部分InSAR资料数据

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。这里给出实体数据。

InSAR data are mainly collected from various research groups. When vertical deformation is significantly greater than horizontal deformation (e.g., 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, the high-precision horizontal deformation provided by GNSS, high-precision vertical deformation from precise leveling, and high-spatial-resolution line-of-sight deformation from InSAR can complement each other through data fusion calculation, which is an attempt intended for this project. However, due to the overly scattered spatial and temporal distribution of the collected datasets and insufficient spatial-temporal matching between different datasets, satisfactory fusion results have not been obtained. Nevertheless, as a compiled and shared dataset, it will demonstrate increasingly important value and significance as more data are accumulated. Actual datasets are provided herein.

背景概述

该数据集是中国大陆地区1997年至2018年的部分InSAR（干涉合成孔径雷达）资料，主要用于监测地壳形变和地面沉降等遥感应用。数据从多个项目组收集而来，由于在时间和空间上分布较为零散，未能与GNSS和精密水准数据有效融合，但作为汇编共享资源，随着数据积累，未来在形变研究中具有重要补充价值。
