National Surface Deformation Map (2024 Edition) is an Earth observation big data cloud service platform independently developed by Beijing Oriental Zhiyuan Co., Ltd. Its core is a national land InSAR-PS point cloud dataset processed via supercomputing, which is constructed based on Sentinel SAR data (Sentinel-1/SLC/IW) 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 mm per year. This platform can provide online real-time millimeter-precision deformation monitoring services for various infrastructure facilities including urban buildings, bridges, subways, roads, dams, and energy facilities. Users can place procurement orders by specifying the required time period and regional scope, and the service offerings include multiple customized options such as cloud service accounts.
