甘肃省龙首山示范区1000 平方公里机载高光谱数据（2022）

甘肃省金昌市龙首山地区1000 平方公里示范区机载高光谱数据。总飞行航带数超过30条，每条航带数据中包括，310个谱段的可见数据、300个谱段的短波数据以及POS数据。其中可见数据和短波数据已完成暗电平扣除、盲元修复、非均匀改正和Etalon效应消除等一系列辐射校正处理，将原始DN值转换为辐亮度，以便后续地物光谱特征参数提取。

Airborne hyperspectral data of the 1000 km² demonstration area located in Longshoushan Region, Jinchang City, Gansu Province. The total number of flight strips exceeds 30. Each strip contains visible data with 310 spectral bands, shortwave data with 300 spectral bands, and POS data. A series of radiometric correction processes, including dark level subtraction, blind pixel correction, non-uniformity correction, and etalon effect elimination, have been applied to the visible and shortwave data, converting the original DN values to radiance to facilitate subsequent extraction of surface spectral feature parameters.
