TLDR
In this paper, a method has been developed for quantitative measurement of vegetation conditions over broad regions using ERTS-1 spectral bands 5 and 7, corrected for sun angle, which is shown to be correlated with aboveground green biomass on rangelands.Abstract:
The Great Plains Corridor rangeland project utilizes natural vegetation systems as phenological indicators of seasonal development and climatic effects upon regional growth conditions. A method has been developed for quantitative measurement of vegetation conditions over broad regions using ERTS-1 MSS data. Radiance values recorded in ERTS-1 spectral bands 5 and 7, corrected for sun angle, are used to compute a band ratio parameter which is shown to be correlated with aboveground green biomass on rangelands.read more

The Use of UAV Mounted Sensors for Precise Detection of Bark Beetle Infestation
TL;DR: Evaluated possibilities of unmanned aerial vehicle (UAV)-mounted low-cost RGB and modified near-infrared sensors for detection of different stages of infested trees at the individual level confirm the assumptions that it is possible to use a low- cost UAV-based sensor for Detection of various stages of bark beetle infestation across seasons.

TL;DR: In this paper, the spatial distribution of evapotranspiration (ET) using remote sensing techniques across the entire Amazon River Basin was obtained using six global ET products (GLEAM, SEBS, ALEXI, CMRSET, MOD16, and SSEBop).

Integrating terrain and vegetation indices for identifying potential soil erosion risk area
TL;DR: Results indicated that there was a significant change in the erosion potential of the watershed and a gradual shifting of lower erosion potential class to next higher erosion potentialclass over the study period.

TL;DR: Fine-grained maps of reproductive numbers and local malaria importation rates were combined to show ‘malariogenic potential’, a first for malaria elimination, and as countries approach elimination, these individual-based measures of transmission risk provide meaningful metrics for planning programmatic responses and prioritizing areas where interventions will contribute most to malaria elimination.

Optimum spectral and geometric parameters for early detection of laurel wilt disease in avocado
TL;DR: In this article, the spatial and spectral requirements for quick and accurate detection of Laurel wilt (LW) are evaluated using ANOVA and two neural networks, multilayer perceptron and radial basis function (RBF).
