Application of red edge band in remote sensing extraction of surface water body: a case study based on GF-6 WFV data in arid area

open access: yesHydrology Research, 2021
This paper mainly researches the application method of red edge band in water body remote sensing extraction. Gaofen-6 (GF-6) WFV data were chosen for the high spatial resolution, more bands, and wide width. Two new methods were proposed: the single-band

Improving Intertidal Reef Mapping Using UAV Surface, Red Edge, and Near-Infrared Data

open access: yesDrones, 2019
Coastal living reefs provide considerable services from tropical to temperate systems. Threatened by global ocean-climate and local anthropogenic changes, reefs require spatially explicit management at the submeter scale, where socioecological processes ...

Expanding the Timeline for Earth’s Photosynthetic Red Edge Biosignature [PDF]

open access: yesThe Astrophysical Journal Letters, 2019
Abstract When Carl Sagan observed the Earth during a Galileo fly-by in 1993, he found a widely distributed surface pigment with a sharp reflection edge in the red part of the spectrum, which, together with the abundance of gaseous oxygen and methane in extreme thermodynamic disequilibrium, were strongly suggestive of the presence of life

Landsat-8 vs. Sentinel-2: examining the added value of sentinel-2’s red-edge bands to land-use and land-cover mapping in Burkina Faso

open access: yesGIScience & Remote Sensing, 2018
The availability of freely available moderate-to-high spatial resolution (10–30 m) satellite imagery received a major boost with the recent launch of the Sentinel-2 sensor by the European Space Agency.

Red edge effect and chromoselective photocatalysis with amorphous covalent triazine-based frameworks. [PDF]

open access: yesNat Commun, 2022
Chromoselective photocatalysis offers an intriguing opportunity to enable a specific reaction pathway out of a potentially possible multiplicity for a given substrate by using a sensitizer that converts the energy of incident photon into the redox ...

Analysis of Vegetation Red Edge with Different Illuminated/Shaded Canopy Proportions and to Construct Normalized Difference Canopy Shadow Index

open access: yesRemote Sensing, 2019
Shadows exist universally in sunlight-source remotely sensed images, and can interfere with the spectral morphological features of green vegetations, resulting in imprecise mathematical algorithms for vegetation monitoring and physiological diagnoses ...
