Siachen Glacier flow velocites from 2018 to 2020

The dataset was created using Sentinel-1/2 and GF-3 satellite data. A total of 168 images were fused, comprising 47 optical images and 121 SAR (Synthetic Aperture Radar) images, to generate the ice flow velocity data for the Siachen Glacier from 2018 to 2020.本数据集采用哨兵-1/2号卫星（Sentinel-1/2）与高分三号卫星（GF-3）的卫星遥感数据构建而成。共计融合168幅影像，其中包含47幅光学影像与121幅合成孔径雷达（Synthetic Aperture Radar）影像，以此生成2018年至2020年锡亚琴冰川（Siachen Glacier）的冰流速度数据。
