Hyperspectral imaging is known for its rich spatial-spectral information. The spectral bands provide the ability to distinguish substances spectra which is substantial for analyzing materials. However, high-dimensional data volume of hyperspectal images is problematic for data storage. In this paper, we present a lossy hyperspectral image compressi...
© 2020 Elsevier B.V. Accurate assessments of soil organic carbon (SOC) stocks are needed at multiple scales given their importance to both local soil health and global C cycles. Rangelands cover 54% of California, representing a large stock of SOC, but existing SOC estimates are uncertain. To improve understanding of fine-resolution SOC stocks in c...

In the warm summer of 2017, a landslide failed from the south-east side of the Col des Clochettes on the top of the underlying Trajo Glacier. The study area is at an elevation of about 3500 m a.s.l. in the Gran Paradiso Massif and can be hardly reached by walking from Cogne (Aosta Valley, NW Italy). Studies conducted by field surveys, photogrammetr...

In many parts of Nigeria, water resource is scarce, and where available, determining their abundance is difficult. In the present paper, various groundwater potential zones for the evaluation of groundwater availability in Enugu State have been delineated using remote sensing and GIS techniques. The satellite images and conventional data obtained f...

Muscat metropolitan area holds the major urban masses and capital investments in Oman. The shoreline significantly varies in its geomorphology, slope, width, land use, and ecosystems. As tsunamis and tropical cyclones in the Indian Ocean are frequent, coastal inundation by sweater is inevitable and losses of lives, infrastructures, and ecosystems a...

The current work presents an integrated approach to maximize groundwater exploitation under Sahara conditions. The approach includes investigation of palaeohydrology, remote sensing data, field verification and geophysical datasets (gravity, aeromagnetic and geoloelectrical data). Results reveal the existence of palaeohydrologic remarks such as; pa...

BackgroundTunisia is one of countries most affected by desertification. Sustainability of its resources, particularly agricultural ones, is closely dependent on it. Studies have multiplied to understand this phenomenon and consequently try to reduce its consequences on society. In recent decades, attempts have been made to find methods of forecasti...

An integration of remote sensing, geographical information system (GIS) and 2D resistivity techniques was used to evaluate the groundwater potential of Obafemi Owode local government area (LGA) in Ogun State, southwestern Nigeria. A composite Landsat 7 image was used to produce land use and lineament of the study area. Advanced space-borne thermal ...

Flood is a catastrophic natural disaster event that is immensely threatening and affecting ecosystems as well as human lives all over the world. Flood frequently occurs in Indian districts during the monsoon season. Districts situated near the rivers are more prone to the flood risk. It is not possible to completely eliminate the flood risk, but it...

Functional riparian areas protect water quality and conserve aquatic systems, plants, and wildlife. Laser-based remote sensing technology offers a high-resolution approach to both characterize and document changes in riparian buffer zones (RBZs). The objectives of this study were to demonstrate a rapid method and model to calculate riparian buffer ...
