RSC: 2025年3月28日缅甸震后高分三号/四号遥感影像数据集

据中国地震台网正式测定，3月28日14时20分在缅甸地区发生7.9级地震，震源深度30公里，震中位于21.85°N，95.95°E。为应对此次地震，方便科研工作者分析、研究此次地震机理及提出应对措施，特共享震后高分三号星和高分四号星遥感影像数据。其中，高分三号是搭载C波段合成孔径雷达（SAR）的微波遥感卫星，其SAR数据具有1米分辨率，可用于地表形变监测和灾情评估，尤其在多云或夜间条件下仍能获取高质量影像。高分四号则是光学遥感卫星，具有50米分辨率的高时效性宽幅成像能力，可快速覆盖大范围震区，提供地表宏观变化信息。两颗卫星数据的协同使用，既可实现高精度的地表形变监测，又能快速获取震区大范围的光学影像，为地震机理研究和灾害评估提供了全面的数据支持。

Officially determined by the China Earthquake Networks Center, a magnitude 7.9 earthquake struck Myanmar at 14:20 on March 28, with a focal depth of 30 km and its epicenter located at 21.85°N, 95.95°E. To address this earthquake and facilitate researchers' analysis, study of the earthquake mechanism and development of response measures, remote sensing image data from the post-earthquake Gaofen-3 and Gaofen-4 satellites are hereby shared. Specifically, Gaofen-3 is a microwave remote sensing satellite equipped with a C-band Synthetic Aperture Radar (SAR). Its SAR data features a 1-meter resolution, which can be used for surface deformation monitoring and disaster assessment, and is capable of acquiring high-quality images even under cloudy or nighttime conditions. Gaofen-4, on the other hand, is an optical remote sensing satellite with 50-meter resolution and high-timeliness wide-swath imaging capabilities, which can quickly cover large-scale earthquake-stricken areas and provide macroscopic surface change information. The collaborative use of data from the two satellites enables both high-precision surface deformation monitoring and rapid acquisition of large-scale optical images of the affected area, providing comprehensive data support for earthquake mechanism research and disaster assessment.
