全国地表形变一张图（2024版）

基于2018年初-2023年底哨兵SAR数据（Sentinel-1/SLC/IW），经过超算处理的全国陆地InSAR-PS点云数据集，点密度每平方公里约1000点，全国总点数约100亿点，分辨率约为40米，形变精度约为4.82毫米每年；用户可指定时间、区域范围进行采购；服务方式包含云平台账号等多种定制化方式This national land InSAR-PS point cloud dataset is generated via supercomputing processing, using Sentinel-1/SLC/IW SAR data collected from early 2018 to the end of 2023. The dataset has a point density of approximately 1,000 points per square kilometer, with a total of about 10 billion points across the country, a spatial resolution of around 40 meters, and a deformation monitoring accuracy of roughly 4.82 millimeters per year. Users can place procurement orders by specifying the desired time and regional scope; the service offerings include various customized solutions such as cloud platform accounts.
