The wide field of view (WFV) imaging system the GaoFen-6 (GF-6) satellite processes four popular spectral bands [blue, green, red, and near-infrared (NIR)] new (costal, yellow, two red edges). However, corresponding reference for these eight from one sensor are insufficient in cross-calibration process WFV; therefore, current methods should be improved. To address this problem, Moderate-Resolut...

This paper present the results of a preliminary study to assess the potential of the visible, NIR and SWIR energy of the EMR in differing iron ores of different grades in a rapid manner using hyperspectral radiometry. Using different iron ore samples from Noamundi mines, Jharkhand, India, certain spectro-radiometric measurements and geochemical analysis were carried out and the results have bee...

Near infrared (NIR) spectroscopy allows rapid estimation of quality traits in fresh fruit. Several portable spectrometers are available the market as a low-cost solution to perform NIR spectroscopy. However, spectrometers, being lower cost than benchtop counterpart, do not cover complete near spectral range. Often sensors either use silicon-based visible and detector 400–1000 nm, or InGaAs-base...

Oil spills in the Niger Delta area can be detected and monitored using this novel technique. Landsat 5 8 images were used to assess various vegetation stress, such as Normalized Difference Vegetation Index, Soil Adjusted Atmospheric Resistant Green Near Infrared Short-wave Infrared, from spill site 2019, non-spill (1992 pre-oil spill) 2020 post-oil events, respectively. There is a substantial d...

Near-infrared spectroscopy (NIRS) allows for the rapid estimation of a wide range wood properties. Typically, NIRS studies on have utilized benchtop spectrometers, but efforts to utilize NIR hyperspectral imaging examine and products increased. Compared systems, has several advantages (speed, visualization spatial variability), data typically lower signal-to-noise ratio as well fewer wavelength...

Light-emitting field-effect transistors (LEFETs) are emerging optoelectronic devices able to display simultaneously electrical switching as and electroluminescence emission light emitting diodes. Lead chalcogenide colloidal quantum dots (CQDs) allow achieving in a very broad spectral range, covering the near-infrared (NIR) short-wavelength infrared (SWIR) regions, which cannot be reached with o...

to nadir-viewed vegetation reflectance data. Variability INTRODUCTION in tissue optical properties was wavelength-dependent. During the past several decades, the tools for vegetation For green foliage, the lowest variation was in the visible remote sensing have evolved significantly. Optical remote (VIS) spectral region and the highest in the near-infrared sensing has expanded from the use of p...

Waters along China coast are very turbid with high concentrations of suspended sediment nearly all the time, especially at the Hangzhou Bay, the Yangtze River estuary and the shoal along Jiangsu province. In these turbid and optically complex waters, the standard MODIS ocean color products tend to have invalid values. Because the water-leaving radiances in the near-infrared (NIR) are significan...
