吉林一号光谱星（JLS-5M）东盟十国数据集（2020）

JLS-5M数据集由吉林一号光谱01/02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 JLS-5M dataset is constructed from remote sensing image data captured by the multispectral imagers aboard the Jilin-1 Spectral 01/02 satellites. Regarding sensor parameters, the dataset has a spatial resolution of 5–20 m and comprises a total of 20 multispectral spectral bands. In terms of spatial coverage, it has achieved two rounds of full coverage over the Belt and Road region within a three-year period. As for its physical properties, the dataset consists of surface reflectance data derived by performing atmospheric correction and orthorectification on the L1-level data collected by the multispectral imagers of the Jilin-1 Spectral 01/02 satellites.
