北京市地表沉降态势感知数据产品

基于开源卫星数据自行加工计算数据，系统周期性自动解算出城市地表沉降成果数据，根据用户兴趣范围形成沉降态势图以及用户感知区域报告，历史数据回溯、趋势研判分析、风险地域评估等数据服务，可以更加准确地为地质灾害隐患区域提供全面的地面沉降信息、风险态势报告，分析其演变规律，及时地掌握地质灾害对地表的影响范围，减少因地表沉降导致的地质灾害对周边居民及环境的影响。 支持以数据报告的方式，将数据结果提供给有需求的用户。

Using open-source satellite data that undergoes self-processing and calculation, the system automatically and periodically derives urban land subsidence outcome data. It generates subsidence situation maps and reports for user-concerned areas based on the user's scope of interest, and offers data services such as historical data backtracking, trend analysis and assessment, and risk zone evaluation. These capabilities enable more accurate provision of comprehensive land subsidence information and risk situation reports for potential geological hazard zones, support analysis of their evolutionary patterns, allow timely acquisition of the scope of surface impacts caused by geological disasters, and mitigate the adverse impacts of geological disasters induced by land subsidence on surrounding residents and the environment. The system supports providing data results to users in need in the form of data reports.
