Validation of the LaSRC Cloud Detection Algorithm for Landsat 8 Images [PDF]

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2019
This study aims at validating the cloud mask produced by the land surface reflectance code (LaSRC) for Landsat 8 data. To detect clouds in optical satellite imagery, LaSRC uses quality assurance (QA) layers, which are produced during the atmospheric correction process. The QA layers include a “cloud mask,” which is based on the estimation of a residual

Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

Irrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

A 30 m terrace mapping in China using Landsat 8 imagery and digital elevation model based on the Google Earth Engine

, 2021
. The construction of terraces is a key soil conservation practice on agricultural land in China providing multiple valuable ecosystem services. Accurate spatial information on terraces is needed for both management and research. In this study, the first

Review of the Salpausselkä ice‐marginal formations in Finland

Journal of Quaternary Science, EarlyView.
ABSTRACT Extensive Salpausselkä ice‐marginal formations were deposited in southern and eastern Finland during the Weichselian deglaciation. These comprise three major ridges (I, II, and III Salpausselkäs) and their eastern counterparts (Tuupovaara, Koitere, and Pielisjärvi), together forming laterally continuous ice‐marginal formations extending ...

A tool for global and regional Landsat 7 and Landsat 8 cross-sensor harmonization

Geocarto International
The Landsat archive can be used to track long-term landscape and environmental changes. However, substantial differences in atmospheric correction algorithms, radiometric resolution, and spectral response functions suggest that harmonization models ...

Analysis of Landsat 8 detection of the interannual variability of grassland curing in Greater Melbourne, Australia

International Journal of Digital Earth, 2020
As one of the main components of Grassland Fire Danger Index, grassland curing degree provides crucial information for determining grassland fire danger. Accurate estimates of grassland curing are critical for determining grassland fire risk.

Landsat-8 data for chromite prospecting in the Logar Massif, Afghanistan [PDF]

Heliyon, 2018
Chromite is widely distributed in the east and southeast of Afghanistan, especially in Logar Province. Chromite mineralization is podiform-type and is hosted in the stratigraphically lowest ultramafic rocks of the Logar Ophiolite Complex. This ophiolite complex represents a remnant of an early Cretaceous oceanic crust that was thrusted over a late ...
