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: The results highlighted that GnyLi and NRI can be used together with hyperspectral images for both plot and regional level biomass estimation, and showed that it performed best with R 2 > 0.74.

Remote Estimation of Rice Yield With Unmanned Aerial Vehicle (UAV) Data and Spectral Mixture Analysis
TL;DR: A new approach which integrated UAV-based vegetation index (VI) and abundance information obtained from spectral mixture analysis (SMA) was established to improve the estimation accuracy of rice yield at heading stage, showing that VI incorporated with abundance information exhibited a better predictive ability for yield than VI alone.

Remote estimation of rapeseed yield with unmanned aerial vehicle (UAV) imaging and spectral mixture analysis
TL;DR: This study gives an important indication that spectral mixture analysis needs to be considered when estimating yield by remotely sensed VI, especially for the image containing obviously spectral different components or for crops which have conspicuous flowers or fruits with significantly different spectra from their leave.

Monitoring boreal forest leaf area index across a Siberian burn chronosequence: a MODIS validation study
TL;DR: In this paper, the MODIS leaf area index (LAI) and vegetation index (VI) were used to study the post-fire chronosequence in the central Siberian region of Krasnoyarsk (57.3°N, 91.6°E).

A rule-based approach for mapping macrophyte communities using multi-temporal aquatic vegetation indices
Paolo Villa,Mariano Bresciani,Rossano Bolpagni,Monica Pinardi,Monica Pinardi,Claudia Giardino +5 more
TL;DR: In this paper, a rule-based classification scheme was implemented for mapping four macrophyte community types (helophyte, emergent rhizophyte and submerged-floating association).
