Abstract
\textit{1) Hyrank dataset:}
The dataset was developed with the support of the ISPRS Scientific Committee, taken by the Hyerion sensor carried by NASA's EO-1 satellite. After screening 242 spectral bands from SWIR and VNIR sensors, 176 spectral bands were exported. The total of 5 images and 14 land-cover categories were provided. The Dioni image size is $250 \times1376 $, and the Loukia image size is $249 \times945 $, both with a spatial resolution of 30m. Two scene images are shown in Fig. \ref{Hyrank}.
\textit{2) Houston dataset:}
The dataset is provided by the NSF funded Airborne Mapping Center at the University of Houston in the IEEE GRSS competition, and was released in 2013 and 2018, respectively. The shooting scene is the campus and surrounding areas of the University of Houston. The spatial resolution is 2.5m, and 144 channels are sampled in the spectral band from 364nm to 1046nm. The Houston2013 consists of 15 categories (excluding unclassified backgrounds) with a spatial size of $349 \times1905 $. The Houston2018 consists of 20 categories (excluding unclassified backgrounds), including 48 spectral channels with a spatial resolution of 1m. The real terrain scenes corresponding to the dataset are shown in Fig. \ref {houston}.
\textit{3) Pavia dataset:}
The Pavia dataset include University of Pavia and Pavia Center datasets were both obtained by the ROSIS sensor of the German airborne reflectance optical spectrometer, which imaged a total of 115 spectral bands ranging from 0.43$\mu$m to 0.86$\mu$m. The spatial resolution is 1.3m. Pavia University is a partial hyperspectral imaging data obtained from Pavia City University in Italy. Excluding 12 severely affected bands from the 115 bands, there are still 103 bands with a size of $610\times340 $. Except the background, there are a total of 42776 ground object pixels, including 9 categories. Pavia Center has 102 bands with a size of $1096\times715$. Fig. \ref {pavia} shows the real ground scenes of University of Pavia and Pavia Center.
