The HyRANK hyperspectral datasets has been developed in the framework of the ISPRS Scientific Initiatives. In particular, the “HyRANK Hyperspectral Satellite Dataset I” contains the openly available Hyperion hyperspectral dataset along with the corresponding reference/ ground truth data. The training set contains two hyperspectral images (i.e., Dioni and Loukia) and the validation set contains three hyperspectral images (i.e., Erato, Nefeli, Kiriki). The HyRANK benchmark platform can be reached through the ISPRS website under the Commission III, Working Group III/4 ‘Hyperspectral Image Processing’ webpage.
