We report on spectral reflectance measurements of basaltic lava flows on Tenerife Island, Spain. Lava flow surfaces of different ages, surface roughness and elevations were systematically measured using a field spectroradiometer operating in the range of 350–2500 nm. Surface roughness, oxidation and lichen coverage were documented at each measured site. Spectral properties vary with age and mor...

It is difficult and time consuming to use traditional measurement methods to estimate the physical properties of snow. However, the emergence of hyperspectral imagery for estimating the physical properties of snow provides a powerful tool. Snow albedo, grain size, and temperature are important factors for evaluating the surface energy balance. Using the spectrum-reflection curves of the differe...

Hyperspectral sensors provide the potential for direct estimation of pasture feed quality attributes. However, remote sensing retrieval of digestibility and fibre (lignin and cellulose) content of vegetation has proven to be challenging since tissue optical properties may not be propagated to the canopy level in mixed cover types. In this study, partial least squares regression on spectra from ...

The Amazon floodplain water composition undergoes intensive variations along the year as a response to the annual flood pulse. The present study analyzes the spectral mixtures of the optically active substances (OAS) in the Amazon floodplain waters with spaceborne hyperspectral images. The test site was located upstream the confluence of Amazon (white water) and Tapajós (clear-water) rivers, wh...

This essay explores some aspects of the complex relationship between prophecies, poems, and dreams in Keats’s poetry. Keats often refers to idea that poetry can alleviate harsh realities human life reconcile ourselves our situation. But poet rely on dreaming imagination achieve this effect? engages a close reading central passages from Hyperion, Odes ‘Bright Star’ which negotiates his competing...

introduction in recent decades, a large variety of science experts, including geology and mine scientists, have considered remote sensing technology as one of the most important instruments to receive information. access to hyper spectral data is one of the main evolutions in the remote sensing technology. the main feature of the technology is its application in identification of minerals and d...
