Medium resolution satellite data, such as Sentinel-2 of the Copernicus programme, offer great new opportunities for agricultural sector, and provide insights on soil surface characteristics their management. Soil monitoring requires a high-quality dataset uncovered plastic covered soil. We developed methodology to identify pixels in parcels during seedbed preparation considered impacts clouds s...

We investigated the utility of high spectral and spatial resolution imagery for the automated species-level classification of individual tree crowns (ITCs) in a tropical rain forest (TRF). Laboratory spectrometer and airborne reflectance spectra (161 bands, 437–2434 nm) were acquired from seven species of emergent trees. Analyses focused on leaf-, pixeland crown-scale spectra. We first describe...

Accurate mapping is prepared using Linear unmixing of satellite images. Endmember extraction contributes the unmixing accuracy. In this paper, Endmembers are extracted using different Geometrical algorithms like Pixel Purity Index (PPI), Nearest Finder (N-FINDR) and Sequential Maximum Angle Convex Cone (SMACC) algorithms. Extracted Endmembers are given as input for unmixing and it is attempted ...

a = bubble radius, m b = corrective factor used in Eq. (10) cij = matrix elements of the sensitivity coefficients J e = sample thickness, m f1, f2 = spectral weights of the Henyey–Greenstein phase function HG g = spectral asymmetry factor g1, g2 = spectral parameters of the Henyey–Greenstein phase function HG I = spectral radiation intensity, W m 2 sr 1 J = matrix of the sensitivity coefficient...

Monitoring of forest cover is an essential tool for sustainable management of natural resources. Woody green cover can better maintained and managed by identification of forest gaps and their subsequent refilling. Forest canopy density mapping is one of the tools used to identify such canopy openings and most useful parameter to consider in the planning and implementation of afforestation and r...

Introduction: Mawrth Vallis, Mars, exhibits unique stratigraphy characterized by distinct phyllosili-cate units across an expansive region [1,2]. A potential analog for this site is the Painted Desert in Arizona, where striking profiles of clay and iron oxide units color the landscape [3]. Both sites contain multiple phyllosilicate units in similar stratigraphy across wide regions. We have acqu...

We present the discovery of a giant cloud ionized gas in field starbursting galaxy M82. Emission from is seen H$\alpha$ and [NII]$\lambda$6583 data obtained though small pathfinder instrument used to test key ideas that will be implemented Dragonfly Spectral Line Mapper, an upcoming ultranarrow-bandpass imaging version Telephoto Array. The discovered has shell-like morphology with linear extent...

Plastic pollution in aquatic ecosystems has increased dramatically the last five decades, with strong impacts on human and life. Recent studies endorse need for innovative approaches to monitor presence, abundance, types of plastic these ecosystems. One approach gaining rapid traction is use multi- hyperspectral cameras. However, most experiments using this were controlled environments, making ...
