The number of spectral bands is 102 for Pavia Centre and 103 for Pavia University. These are two scenes acquired by the ROSIS sensor during a flight campaign over Pavia, nothern Italy. Groundtruth of Salinas-A dataset Groundtruth classes for the Salinas-A scene and their respective samples number Download MATLAB data files: Salinas (26.3 MB) | corrected Salinas (25.3 MB) | Salinas groundtruth (4.2 KB).It includes vegetables, bare soils, and vineyard fields.
This image was available only as at-sensor radiance data. As with Indian Pines scene, we discarded the 20 water absorption bands, in this case bands:, , 224. The area covered comprises 512 lines by 217 samples. This scene was collected by the 224-band AVIRIS sensor over Salinas Valley, California, and is characterized by high spatial resolution (3.7-meter pixels). Groundtruth of Indian Pines dataset Groundtruth classes for the Indian Pines scene and their respective samples number Download MATLAB data files: Indian Pines (6.0 MB) | corrected Indian Pines (5.7 MB) | Indian Pines groundtruth (1.1 KB).Indian Pines data are available through Pursue's univeristy MultiSpec site. We have also reduced the number of bands to 200 by removing bands covering the region of water absorption:, , 220. The ground truth available is designated into sixteen classes and is not all mutually exclusive. Since the scene is taken in June some of the crops present, corn, soybeans, are in early stages of growth with less than 5% coverage. There are two major dual lane highways, a rail line, as well as some low density housing, other built structures, and smaller roads. The Indian Pines scene contains two-thirds agriculture, and one-third forest or other natural perennial vegetation. This scene was gathered by AVIRIS sensor over the Indian Pines test site in North-western Indiana and consists of 145\times145 pixels and 224 spectral reflectance bands in the wavelength range 0.4–2.5 10^(-6) meters.
