2019年新疆哈密示范区高分5号卫星高光谱（5nm）模拟数据集

使用DEM数据获取新疆哈密地区的三维地形信息，结合野外地物实测反射率光谱，以及地表矿物分类信息，即可获取辐射传输模型（WPS）需要的三维结构信息和光谱反射率输入数据，加上WPS的地气耦合模块，获取传感器处的高光谱入瞳辐亮度信息，模拟生成遥感图像。模拟光谱与实测光谱对比验证结果表明，两者具有较好一致性，回归结果的RMSE为0.0109，R2为0.9984。

Three-dimensional terrain information of the Hami region in Xinjiang was acquired using DEM data. Combined with in-situ measured reflectance spectra of surface features and surface mineral classification information, the three-dimensional structural information and spectral reflectance input data required by the radiative transfer model (WPS) were obtained. Coupled with the land-atmosphere coupling module of WPS, hyperspectral at-sensor radiance information was acquired, and remote sensing images were simulated and generated. The comparison and validation between the simulated and measured spectra demonstrate good consistency, with the regression yielding an RMSE of 0.0109 and an R² of 0.9984.
