吉林一号光谱星（JL1GP02-5M）- 中国（2020-2021）

JL1GP02-5M数据集由吉林一号光谱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19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 JL1GP02-5M dataset is developed from remote sensing imagery captured by the multispectral imager onboard the Jilin-1 Spectral 02 Satellite. In terms of sensor specifications, the dataset has a spatial resolution of 5–20 m and includes a total of 19 multispectral bands. Regarding spatial coverage, the dataset provides two revisit passes over the Belt and Road region within a 3-year timeframe. In terms of physical properties, this dataset comprises surface reflectance data obtained by performing atmospheric correction and orthorectification on the L1-level data collected by the satellite’s multispectral imager.
