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

TL;DR: In this article, the authors used spectral vegetation indices (VIs) obtained from satellite images of the MODIS sensor in 194 sites located across the Patagonian steppe to assess the spatial variability of ecosystem structure and functioning.

Wetland changes of China's largest freshwater lake and their linkage with the Three Gorges Dam
TL;DR: Wang et al. as mentioned in this paper presented the spatial and temporal changes of the major wetland cover types from 2000 to 2014, showing that the vegetation compositions are primarily controlled by water depth, indicating that the recent wetland changes can be directly linked to the TGD-induced hydrological regime-shift.

TL;DR: Except the maximum temperature difference (MTD), all parameters derived from different sensors were significantly correlated with each other and with disease severity (DS).

A land cover change detection and classification protocol for updating Alaska NLCD 2001 to 2011.
TL;DR: In this article, the authors developed a comprehensive approach named AKUP11 to update Alaska NLCD from 2001 to 2011 and provide a 10-year cyclical update of the state's land cover and land cover changes.

Estimation of Actual Crop Coefficients Using Remotely Sensed Vegetation Indices and Soil Water Balance Modelled Data
TL;DR: The proposed methods for estimating actual basal crop coefficients from vegetation indices considering a density coefficient (Kd) and a crop coefficient for bare soil show that the proposed methods are adequate for supporting irrigation management.
