Modified shape index for object-based random forest image classification of agricultural systems using airborne hyperspectral datasets.

PLoS ONE, 2019
This paper highlights the importance of optimized shape index for agricultural management system analysis that utilizes the contiguous bands of hyperspectral data to define the gradient of the spectral curve and improve image classification accuracy ...

DIRECT ESTIMATION OF ABOVEGROUND FOREST PRODUCTIVITY THROUGH HYPERSPECTRAL REMOTE SENSING OF CANOPY NITROGEN [PDF]

, 2002
The concentration of nitrogen in foliage has been related to rates of net photosynthesis across a wide range of plant species and functional groups and thus represents a simple and biologically meaningful link between terrestrial cycles of carbon and ...

Estimating flavonoids using radiative transfer model inversion on imaging spectroscopy data

Frontiers in Remote Sensing
Assessing flavonoid content is crucial for understanding plant responses to biotic and abiotic stresses. However, pigments such as chlorophylls, carotenoids, and anthocyanins, absorb light between 410 and 430 nm, thus makes it difficult to quantify ...

Identification of a Potential Rare Earth Element Deposit at Ivanpah Dry Lake, California Through the Bastnäsite Indices

Remote Sensing
A groundbreaking remote sensing approach that uses three Bastnäsite Indices (BI) to detect rare earth elements (REEs) was initially developed using ore samples from the Sulfide Queen mine in California and later applied to various well-studied ground ...
