青藏高原100米遥感影像图（2015-2019）

该数据为2015-2019年间覆盖青藏高原科考范围7个卫星轨道的Landsat多光谱遥感影像数据。基于Google Earth Engine平台调用多时相的Landsat卫星 30 m影像数据镶嵌各景数据，降采样至100 m分辨率，并调整直方图校正色调，根据青藏科考范围矢量文件裁剪获得可以清晰显示青藏高原科考范围内地形地貌的高分辨率遥感影像数据。图集内包含了青藏高原科考范围内活动断裂分布数据。青藏高原所处区域，范围的划定依据任务九的工作调查研究范围（经度范围66.28°-106.63°E, 纬度范围21.64°-46.11°N）。数据集/图集内容表征的空间基准为2000国家大地坐标系（CGCS-2000）；空间分辨率为100 m。

This dataset includes Landsat multispectral remote sensing image data spanning 7 satellite orbits within the scope of the Qinghai-Tibet Plateau scientific expedition during 2015–2019. Multi-temporal Landsat 30 m satellite imagery was acquired via the Google Earth Engine platform, with individual scenes mosaicked, downsampled to 100 m resolution, and tone-corrected via histogram adjustment. The processed imagery was then clipped using the vector file of the Qinghai-Tibet Plateau scientific expedition scope to generate high-resolution remote sensing image data that clearly displays the topography and landforms within the expedition area. This dataset atlas also contains active fault distribution data within the Qinghai-Tibet Plateau scientific expedition scope. The regional coverage of this dataset is defined based on the work survey and research scope of Task 9, with a longitude range of 66.28°–106.63°E and latitude range of 21.64°–46.11°N. The spatial reference system of the dataset/atlas is China Geodetic Coordinate System 2000 (CGCS2000), with a spatial resolution of 100 m.
