Retinal nerve fiber layer reflectometry must consider directional reflectance. [PDF]
Biomed Opt Express, 2016 Recent studies reveal that measurements of retinal nerve fiber layer (RNFL) reflectance provide more sensitive detection of glaucomatous damage than RNFL thickness, but most do not consider directional reflectance of the RNFL, an important source of ...

Fine-resolution mapping of microforms of a boreal bog using aerial images and waveform-recording LiDAR [PDF]
Mires and Peat, 2020 Boreal bogs are important stores and sinks of atmospheric carbon whose surfaces are characterised by vegetation microforms. Efficient methods for monitoring their vegetation are needed because changes in vegetation composition lead to alteration in their

Tree species identification in aerial image data using directional reflectance signatures
Silva Fennica, 2014 Tree species identification using optical remote sensing is challenging. Modern digital photogrammetric cameras enable radiometrically quantitative remote sensing and the estimation of reflectance images, in which the observations depend largely on the ...

Airborne measurements of directional reflectivity over the Arctic marginal sea ice zone [PDF]
Atmospheric Measurement Techniques, 2022 The directional reflection of solar radiation by the Arctic Ocean is mainly shaped by two dominating surface types: sea ice (often snow-covered) and open ocean (ice-free).

Functional Data Analysis of Multi-Angular Hyperspectral Data on Vegetation
Aceh International Journal of Science and Technology, 2012 The surface reflectance anisotropy can be estimated by directional reflectance analysis through the collection of multi-angular spectral data. Proper characterization of the surface anisotropy is animportant element in the successful interpretation of ...
