吉林一号光谱星（JL1GP01-5M）- 伊拉克（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. Regarding sensor parameters, this dataset has a spatial resolution of 5–20 m and a total of 20 multispectral spectral bands. Spatially, this dataset provides two revisit coverages of the Belt and Road Initiative (BRI) area within three years. For its physical characteristics, this dataset consists of surface reflectance data obtained after performing atmospheric correction and orthorectification on the L1-level data from the Jilin-1 Spectral 01 Satellite’s onboard multispectral imager.
