Airborne hyperspectral data

Hyperspectral imagery was acquired with a AISA FENIX 1K camera collecting data from the visible to the shortwave infrared [0.38 - 2.5 µm] in 420 spectral bands.

The provided dataset is divided in 25 tiles (~14 Go each tile)

Camera calibration was achieved in lab and controlled during the flight when passing over reference targets.

Atmospheric correction was done with COCHISE, using atmospheric profiles from METEO-FRANCE and aerosols in situ measurements provided by a CIMEL spectroradiometer.
Ortho-rectification was achieved thanks to DEM provided by RGE ALTI 1m database of IGN.

Camera caracteristics:
Swath: 1024 m ;
Ground Sample Distance: 1 m ;
Spectral resolution:
~3.6 nm between 380 - 970 nm ;
~7.8 nm between 970 - 2500 nm.

The data are provided as ortho-rectified tiles (UTM 31N) in surface reflectance in ENVI format. Check the README file to get more information on the data organisation and characteristics.

本数据集采用AISA FENIX 1K相机获取高光谱影像，该相机可采集可见光至短波红外波段（0.38~2.5 μm）范围内的光谱数据，共包含420个光谱波段。
本数据集被划分为25个影像瓦片，每个影像瓦片大小约14吉字节。
相机已在实验室完成标定，并在飞行过程中通过飞越参考靶标进行了精度管控。
大气校正采用COCHISE工具完成，所用大气廓线数据来自法国气象局（METEO-FRANCE），气溶胶原位测量数据则由CIMEL光谱辐射计提供。
正射校正借助法国国家地理学会（IGN）的RGE ALTI 1m数据库提供的数字高程模型（DEM）完成。
相机参数如下：
幅宽：1024米；
地面采样距离：1米；
光谱分辨率：
380~970 nm波段区间内约为3.6 nm；
970~2500 nm波段区间内约为7.8 nm。
本数据集以地表反射率形式提供，为经过正射校正的影像瓦片（UTM 31N坐标系），存储格式为ENVI格式。请查看README文件以获取更多关于数据组织与参数特性的详细信息。
