Uncalibrated and noisy bands that cover water absorption features were removed, and the remaining 145 bands were included as candidate features. Preprocessing of the data was performed by the UT Center for Space Research to mitigate the effects of bad detectors, inter-detector miscalibration, and intermittent anomalies. The Hyperion sensor on EO-1 acquires data at 30 m pixel resolution over a 7.7 km strip in 242 bands covering the 400-2500 nm portion of the spectrum in 10 nm windows. The NASA EO-1 satellite acquired a sequence of data over the Okavango Delta, Botswana in 2001-2004. * Corrected version offered by Ilya Kavalerov Botswana Download MATLAB ground truth file: KSC gt (3.2 kB).Download MATLAB data file: Kennedy Space Center (KSC) (56.8 MB).For classification purposes, 13 classes representing the various land cover types that occur in this environment were defined for the site. Discrimination of land cover for this environment is difficult due to the similarity of spectral signatures for certain vegetation types. The vegetation classification scheme was developed by KSC personnel in an effort to define functional types that are discernable at the spatial resolution of Landsat and these AVIRIS data. Training data were selected using land cover maps derived from color infrared photography provided by the Kennedy Space Center and Landsat Thematic Mapper (TM) imagery. After removing water absorption and low SNR bands, 176 bands were used for the analysis. The KSC data, acquired from an altitude of approximately 20 km, have a spatial resolution of 18 m. AVIRIS acquires data in 224 bands of 10 nm width with center wavelengths from 400 - 2500 nm. The NASA AVIRIS (Airborne Visible/Infrared Imaging Spectrometer) instrument acquired data over the Kennedy Space Center (KSC), Florida, on March 23, 1996. Download MATLAB data files: Pavia Centre (123.6 MB) | Pavia Centre groundtruth (34.1 KB).Paolo Gamba from the Telecommunications and Remote Sensing Laboratory, Pavia university (Italy). It can be seen the discarded samples in the figures as abroad black strips. Both image groundtruths differenciate 9 classes each. Pavia Centre is a 1096*1096 pixels image, and Pavia University is 610*610 pixels, but some of the samples in both images contain no information and have to be discarded before the analysis. 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.
