HySpecNet-11k is a large-scale hyperspectral benchmark dataset made up of 11,483 nonoverlapping image patches acquired by the EnMAP satellite. Each patch is a portion of 128 × 128 pixels with 224 spectral bands and with a ground sample distance of 30 m.

We have manually labeled each image in the UC-Merced archive with one or more (maximum seven) labels based on visual inspection in order to create the ground reference data. The total number of distinct class labels associated for the considered archive is 17.

The Ankara benchmark archive consists of 216 hyperspectral image tiles obtained by fragmenting a hyperspectral image acquired by EO-1 Hyperion sensor over surroundings of Ankara, Turkey. Each image tile has been annotated with: i) multiple land-cover class labels and ii) a land-use category label.
