2025年1月7日定日县震后高分一号/三号遥感影像数据集

据中国地震台网正式测定，1月7日9时5分在西藏日喀则市定日县发生6.8级地震，震源深度10公里，震中位于北纬28.50度，东经87.45度。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，特共享震后高分一号C星和高分三号B星遥感影像数据。其中，高分一号C星是光学遥感卫星，具有2米全色和8米多光谱分辨率，可提供高精度的地表光学影像；高分三号B星则是搭载C波段合成孔径雷达（SAR）的微波遥感卫星，其SRA数据可用于地表形变监测和灾情评估。两颗卫星数据的协同使用，既可获取震区精细的地表信息，又能实现地表变形监测，为地震机理研究和灾害评估提供了重要的数据支持。

Officially confirmed by the China Earthquake Networks Center, a magnitude 6.8 earthquake occurred in Dingri County, Xigaze City, Tibet Autonomous Region at 09:05 on January 7, with a focal depth of 10 kilometers, and the epicenter located at 28.50° north latitude and 87.45° east longitude. To respond to this earthquake and facilitate researchers to analyze and study the earthquake mechanism and propose response measures, the post-earthquake remote sensing image data acquired by Gaofen-1 C and Gaofen-3 B satellites are hereby shared. Specifically, Gaofen-1 C is an optical remote sensing satellite with 2-meter panchromatic and 8-meter multispectral resolution, capable of providing high-precision surface optical images; Gaofen-3 B is a microwave remote sensing satellite equipped with a C-band synthetic aperture radar (SAR), and its SAR data can be used for surface deformation monitoring and disaster assessment. The coordinated use of data from the two satellites can not only obtain fine surface information of the earthquake-stricken area, but also realize surface deformation monitoring, providing important data support for earthquake mechanism research and disaster assessment.
