AVHRR-Based Spectral Vegetation Index for Quantitative Assessment of Vegetation State and Productivity: Calibration and Validation
The goal of the work was to estimate, quantitatively, vegetation state and productivity using AVHRR-based Vegetation Condition Index (VCI). The VCI algorithm includes application of post-launch calibration to visible channels, calculation of NDVI from channels’ reflectance, removal of high-frequency noise from NDVI’s annual time series, stratification of ecosystem resources, and separation of e...
متن کاملTest of Multi-spectral Vegetation Index for Floating and Canopy-forming Submerged Vegetation
Remote sensing of terrestrial vegetation has been successful thanks to the unique spectral characteristics of green vegetation, low reflectance in red and high reflectance in Near-InfraRed (NIR). These spectral characteristics were used to develop vegetation indices, including Normalized Difference Vegetation Index (NDVI). However, the NIR absorption by water and light scattering from suspended...
متن کاملGlyphosate and dicamba herbicide tank mixture effects on native plant and non-genetically engineered soybean seedlings.
Crops engineered to contain genes for tolerance to multiple herbicides may be treated with several herbicides to manage weeds resistant to each herbicide. Thus, nearby non-target plants may be subjected to increased exposure to several herbicides used in combination. Of particular concern are native plants, as well as adjacent crops which have not been genetically engineered for tolerance to he...

متن کاملQuantifying Vegetation Change in Semiarid Environments: Precision and Accuracy of Spectral Mixture Analysis and the Normalized Difference Vegetation Index
Because in situ techniques for determining vegetation even when applied to areas of low vegetation cover, the SMA approach correctly determined the sense of change abundance in semiarid regions are labor intensive, they usually are not feasible for regional analyses. Remotely (i.e., positive or negative) in 87% of the samples. SMA results are superior to NDVI, which, although correlated sensed ...
