Multispec remote sensing12/20/2023 ![]() Jasper Ridge and its ground truth (GT: abundances and GT: endmembers ). There are four endmembers latent in this data: "#1 Road", "#2 Soil", "#3 Water" and "#4 Tree".įigure 3. After removing the channels 1-3, 108-112, 154-166 and 220-224 (due to dense water vapor and atmospheric effects), we remain 198 channels (this is a common preprocess for HU analyses). The first pixel starts from the (105,269)-th pixel in the original image. Since this hyperspectral image is too complex to get the ground truth, we consider a subimage of 100 x 100 pixels. Each pixel is recorded at 224 channels ranging from 380 nm to 2500 nm. #2: Japser Ridge (if helpful, please cite the related paper in BibTex) Jasper Ridge is a popular hyperspectral data used in. Ground Truth: GroundTruth.zip (275Kb) includes G T: abundances and GT: endmembers. Data in the Matlab format with 156 channels: Data_Matlab.zip (3.41Mb).Data in the Envi format with 156 channels: Data_Envi.zip (1.47Mb).Samson and its ground truths (GT: abundances and GT: endmembers). "#1 Soil", "#2 Tree" and "#3 Water" respectively.įigure 2. Specifically, there are three targets in this image, i.e. This data is not degraded by the blank channel or badly noised channels. It starts from the (252,332)-th pixel in the original image. As the original image is too large, which is very expensive in terms of computational cost, a region of 95 x 95 pixels is used. The spectral resolution is highly up to 3.13 nm. Each pixel is recorded at 156 channels covering the wavelengths from 401 nm to 889 nm. In this image, there are 952x 952 pixels. #1: Samson (if helpful, please cite the related paper in BibTex) Samson is a simple dataset that is available from the website. Please cite our papers summarized in BibTex if you use any part of our source code or data in your research. Besides, we provide the corresponding ground truths, which are achieved via the method provided in. We give the real dataset in the format of ".img" (Envi) and ".mat" (Matlab). Samson, Jasper Ridge, Urban and Cuprite.įig. Indian Pines data are available through Pursue's univeristy MultiSpec site.ĭownload MATLAB data files: Indian Pines (6.0 MB) | corrected Indian Pines (5.7 MB) | Indian Pines groundtruth (1.1 KB)įigure 1. 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.
