Multiple DJI drone flights with hyperspectral camera over forests in Lithuania #2

Hyperspectral data in all of the datasets consist of processed hyperspectral data cubes to radiance values.all data cubes with _radiance.dat and ._radiance.hdr files are for ENVI format data file. While _rect.dat and _rect.hdr files are ENVI files with georectification applied. Hyperspectral data also contain calculated RGB and NDVI png and tiff images. Png images are generated from _radiance.dat files and tiff images are generated from _rect.dat files that have georectification. All hyperspectral data was collected using the Specim hyperspectral pushbroom camera. ### Hyper 2 https://art21-icaerus.s3.eu-central-1.amazonaws.com/Hyper_2.zip Dataset consists of 7 flight lines filmed over an infected forest. Each flight folder denoted by fl# contains processed hyperspectral data cubes and "processed" folder with RGB and NDVI images. Dataset zip size: 23.4 GB本数据集所有高光谱数据（hyperspectral data）均为已预处理至辐射亮度值的高光谱数据立方体。带有`_radiance.dat`与`_radiance.hdr`后缀的数据立方体均为ENVI格式数据文件；而带有`_rect.dat`与`_rect.hdr`后缀的ENVI文件则已完成地理校正。 本高光谱数据集还包含计算生成的RGB与归一化差分植被指数（NDVI，Normalized Difference Vegetation Index）的PNG及TIFF图像。其中PNG图像由`_radiance.dat`文件生成，TIFF图像则由已完成地理校正的`_rect.dat`文件生成。 所有高光谱数据均通过Specim推扫式高光谱相机采集获取。 ### Hyper 2 https://art21-icaerus.s3.eu-central-1.amazonaws.com/Hyper_2.zip 该数据集包含7条拍摄于受侵染林区的飞行航线数据。每条以`fl#`命名的飞行航线文件夹中均包含已预处理的高光谱数据立方体，以及存储RGB与NDVI图像的`processed`子文件夹。 数据集压缩包大小：23.4 GB
