吉林一号光谱星（JL1GP01-5M）- 塔吉克斯坦（2021-2023）

JL1GP01-5M数据集由吉林一号光谱01卫星的多光谱成像仪所拍摄的遥感影像数据制作、构建而成。在传感器参数方面,该数据集的空间分辨率为5-20m,共有20个多光谱谱段。在空间范围方面,该数据集对“一带一路”区域实现3年内2次覆盖。在物理属性方面,该数据集为对光谱卫星多光谱成像仪的L1级数据进行大气校正和正射校正后的地表反射率数据。

The JL1GP01-5M dataset is constructed from remote sensing image data captured by the multispectral imager onboard the Jilin-1 Spectral 01 Satellite. In terms of sensor specifications, this dataset has a spatial resolution of 5–20 m and includes a total of 20 multispectral spectral bands. For spatial coverage, the dataset has obtained two overpasses of the Belt and Road Initiative (BRI) region within a three-year period. Regarding physical attributes, this dataset consists of surface reflectance data derived from the L1-level data of the satellite’s multispectral imager after undergoing atmospheric correction and orthorectification.
