The freedles project sets out to develop a universal method for quantifying clumping of foliage in forests based on detailed 3d structure and spectral reflectance

of the wheat cultivars at the Feekes growth stage 10.
Within this context, the objective of this study was to characterize the variability of spectral reflectance
and temporal profiles of vegetation indices associated with nitrogen fertilization, crop cycle periods, and predominating weather conditions during the winter canola growing season in southern Brazil.
The obvious question that arises from this discussion is why the band was positioned outside the green peak of the vegetation spectral reflectance
Their topics include digital philology between Alexander and Babel, taking a fresh start on categories of ancient Christian texts and writing materials, digital editing and the Greek New Testament, the "Thesaurus Gregorianus," an Internet database of Gregorian office antiphons, new technology for imaging unreadable manuscripts and other artifacts: integrated spectral reflectance
transformation imaging, and digital resources of the Rabbinic literature: radical change with a click of the mouse.
Many researchers have attempted to estimate chlorophyll content using light reflectance and/or the vegetation index (VI) (ratio combining information contained in two spectral bands to derive vegetation greenness and canopy characteristics) because measurement of spectral reflectance
provides a rapid, nondestructive method for pigment estimation (Thomas and Gausman, 1977; Sims and Gamon, 2002).
Estimation of severity level of wheat powdery mildew based on canopy spectral reflectance
The resultant spectral reflectance
of a metal film having an island structure (film composed of small metal particles) is different from that of bulk, and therefore, the film shows a unique color tone.
The implementation of the physical relation between spectral reflectance
and light attenuation is the base of extracting information from multispectral satellite imagery over water bodies.
Third, the soil moisture was altered by uniformly spraying the sample 17 times with water, and the spectral reflectance
and weight of each sample were measured after each sample was permeated completely by water.
Labcell has introduced the Decagon Devices SRS Spectral Reflectance
Sensors for measuring NDVI (normalised differential vegetation index) and PRI (photochemical reflectance index) at the plot or plant stand scale.
