(1) SAR Sentinel-1 Satellite Imagery in VV & VH polarization

The Sentinel-1 SAR imagery, in the Interferometric Wide (IW) mode, C-band, with dual polarization VV (Vertical transmit Vertical receive), VH (Vertical transmit Horizontal receive), was acquired on 1 March 2017 from Kuh Sefid district, which is a village located in the Central District of Qom County, Qom, Iran. This area, which has a hot and dry climate with annual precipitation of about 115.5 mm, the highest temperature of 39.7 °C in July and the lowest temperature of 0.4 °C in December, is affected by severe salinity hazard mainly due to the vicinity to the Salt Lake Qom. The surface soil texture in this region varies between silt loams to silty clay loam, which has a yellowish brown to dark brown color.

(4) The Soil Moisture Active Passive Validation Experiment 2016 (SMAPVEX16-MB)

The Soil Moisture Active Passive Validation Experiment 2016 (SMAPVEX16-MB) campaign was conducted over an agricultural test site (Figure) measuring 26 km × 48 km and located in southern Manitoba (Canada). Numerous SAR experiments have been conducted over this site, spanning several decades (Bhuiyan et al., 2018). The site is dominated by annual agricultural production with a diverse crop mix that includes canola, corn, soybean, wheat and oats. The SMAPVEX16-MB was conducted during the summer of 2016 and was focused on the monitoring of soil surface and crop. Soil surface moisture and roughness, and vegetation water content (VWC) were mainly collected. Soil surface moisture are available at the depth of 5, 10, 20, 50 cm. The distribution of the ground sites is shown in Figure.For more information "H. McNairn et al., "SMAPVES-16 Experimental Plan," 1–71 (2016)".

Hyperspectral Datasets

Here you can find information over some public available hyperspectral scenes. All of them are Earth Observation images taken from airborne or satellites.

 

(1) Indian Pines

This scene was gathered by AVIRIS sensor over the Indian Pines test site in North-western Indiana and consists of 145´145 pixels and 224 spectral reflectance bands in the wavelength range 0.4–2.5 10-6 meters. This scene is a subset of a larger one. The Indian Pines scene contains two-thirds agriculture, and one-third forest or other natural perennial vegetation. There are two major dual lane highways, a rail line, as well as some low density housing, other built structures, and smaller roads. 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. The ground truth available is designated into sixteen classes and is not all mutually exclusive. We have also reduced the number of bands to 200 by removing bands covering the region of water absorption: [104-108], [150-163], 220. Indian Pines data are available through Pursue's univeristy MultiSpec site.

(4) Cuprite

This data sets can be retrieved from AVIRIS NASA site. Among the many datasets available, the. mat archive posted here corresponds to the f970619t01p02_r02_sc03.a.rfl reflectance file. Cuprite is the most benchmark dataset for the hyperspectral unmixing research that covers the Cuprite in Las Vegas, NV, U.S. There are 224 channels, ranging from 370 nm to 2480 nm. After removing the noisy channels (1-2 and 221-224) and water absorption channels (104-113 and 148-167), we remain 188 channels. Aregion of 250x190 pixels is considered, where there are 14 types of minerals. Since there are minor differences between variants of similar minerals, we reduce the number of endmembers to 12, which are summarized as follows "#1 Alunite", "#2 Andradite", "#3 Buddingtonite", "#4 Dumortierite", "#5 Kaolinite1", "#6 Kaolinite2", "#7 Muscovite", "#8 Montmorillonite", "#9 Nontronite", "#10 Pyrope", "#11 Sphene", "#12 Chalcedony".

(5) Kennedy Space Center (KSC)

The NASA AVIRIS (Airborne Visible/Infrared Imaging Spectrometer) instrument acquired data over the Kennedy Space Center (KSC), Florida, on March 23, 1996. AVIRIS acquires data in 224 bands of 10 nm width with center wavelengths from 400 - 2500 nm. The KSC data, acquired from an altitude of approximately 20 km, have a spatial resolution of 18 m. After removing water absorption and low SNR bands, 176 bands were used for the analysis. 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. 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. Discrimination of land cover for this environment is difficult due to the similarity of spectral signatures for certain vegetation types. For classification purposes, 13 classes representing the various land cover types that occur in this environment were defined for the site.

(6) Botswana

The NASA EO-1 satellite acquired a sequence of data over the Okavango Delta, Botswana in 2001-2004. 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. Preprocessing of the data was performed by the UT Center for Space Research to mitigate the effects of bad detectors, inter-detector mis-calibration, and intermittent anomalies. Un-calibrated and noisy bands that cover water absorption features were removed, and the remaining 145 bands were included as candidate features: [10-55, 82-97, 102-119, 134-164, 187-220]. The data analyzed in this study, acquired May 31, 2001, consist of observations from 14 identified classes representing the land cover types in seasonal swamps, occasional swamps, and drier woodlands located in the distal portion of the Delta.

(7) Samson

Samson is a simple dataset that is available from the website. In this image, there are 952x952 pixels. Each pixel is recorded at 156 channels covering the wavelengths from 401 nm to 889 nm. The spectral resolution is highly up to 3.13 nm. As the original image is too large, which is very expensive in terms of computational cost, a region of 95x95 pixels is used. It starts from the (252,332)-th pixel in the original image. This data is not degraded by the blank channel or badly noised channels. Specifically, there are three targets in this image, i.e. "#1 Soil", "#2 Tree" and "#3 Water" respectively.

(8) Jasper Ridge

Jasper Ridge is a popular hyperspectral dataset. There are 512x614 pixels in it. Each pixel is recorded at 224 channels ranging from 380 nm to 2500 nm. The spectral resolution is up to 9.46nm. Since this hyperspectral image is too complex to get the ground truth, we consider a sub image of 100x100 pixels. The first pixel starts from the (105,269)-th pixel in the original image. 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). There are four endmembers latent in this data: "#1 Road", "#2 Soil", "#3 Water" and "#4 Tree".

(9) Urban

Urban is one of the most widely used hyperspectral data used in the hyperspectral unmixing study. There are 307x307 pixels, each of which corresponds to a 2x2 m2 area. In this image, there are 210 wavelengths ranging from 400 nm to 2500 nm, resulting in a spectral resolution of 10 nm. After the channels 1-4, 76, 87, 101-111, 136-153 and 198-210 are removed (due to dense water vapor and atmospheric effects), we remain 162 channels (this is a common preprocess for hyperspectral unmixing analyses).

(13) The Cooke City Dataset (Target Detection Dataset)

Recently, Khoshboresh-Masouleh and Hasanlou (2020) introduced a revised replacement signal model for improving hyperspectral sub-pixel target detection in multiple target signatures. In this paper, the hyperspectral image with coverage areas of approximately 2.0 km2 in Cooke City town, MT, USA is used as the experimental data. It was provided via the HyMap airborne hyperspectral imaging sensor by Snyder et al., (2008). HyMap sensor flown at 1.4 km above the ground level. The Cooke City dataset is illustrated in Fig. 1a, where there are 280×800 pixels. Each pixel is observed at 126 bands covering the electromagnetic spectra from 0.45 to 2.48 μm and the ground sample distance is 3.0 m. In this study, the three vehicles (Fig. 1b- d) and four fabric panels (Fig. 1e-h) in different sizes and colors were selected as targets. The reference spectra of the vehicles and the fabric panels were measured by an Analytical Spectral Devices, Inc. FieldSpec Pro, and a Cary 500 spectrophotometer, respectively. The vehicles were occupied at most a few pixels, but fabric panels F1 and F2 were nearly a full pixel while fabric panels F3 and F4 were occupied less than a pixel. The public open-source dataset used to support this study is available at http://dirsapps.cis.rit.edu/blindtest/.
