Shortcomings of the normalized difference vegetation index as an exposure metric
Nature Plants, 2022The health benefits of exposure to trees and plants is a rapidly expanding field of study. Research has shown that exposure is associated with improvements in a wide range of health outcomes including cardiovascular disease, birth outcomes, respiratory disease, cancer, mental health and all-cause mortality1.

THE NORMALIZED DIFFERENCE VEGETATION INDEX AS AN INDICATOR OF DYNAMICS
GEOLINKS Conference Proceedings, 2021Mediterranean ecosystems are considered particularly sensitive to climate change. Any change in climatic factors affects the structure and functioning of these ecosystems and has an influence on plant productivity. The main objective of this work is to characterize one of the Mediterranean ecosystems; the Chettaba forest massif (located in the North ...

Why Normalized Difference Vegetation Index (NDVI)?
2022Plants play a very important role in ecological systems -- they transform CO2 into oxygen. It is therefore very important to be able to estimate the overall amount of live green vegetation in a given area. The most efficient way to provide such a global analysis is to use remote sensing, i.e., multi-spectral photos taken from satellites, drones, planes,

Temporal influences on normalized difference vegetation index
Proceedings of SPIE, 2008Normalized difference vegetation index (NDVI) is defined as a ratio of the difference of the infrared and red bands to the sum of the two bands. It can be estimated directly from satellite data, and has been widely used in numerous environmental studies. Yet the satellite-based NDVI was criticized for its variations with temporal factors (e.g.

Trend of normalized difference vegetation index (NDVI) over Turkey
Remote Sensing for Agriculture, Ecosystems, and Hydrology XX, 2018Ecosystem productivity, biome distribution, and forest carbon stocks are likely to be changed by the climate change. These ecosystems changes can be identified using Satellite based normalized difference vegetation index (NDVI). In this study, global inventory modeling and mapping studies (GIMMS) NDVI data acquired by the advanced very highresolution ...

Forecasting of the normalized difference vegetation index time series in Jbeniana
2018 4th International Conference on Advanced Technologies for Signal and Image Processing (ATSIP), 2018This paper deals with the study of the vegetation cover variation through the Normalized Difference Vegetation Index (NDVI) in the area of Jbeniana (Sfax, Tunisia). For this purpose, we use the images given by Sentinel-2. This allows us to present the time series of NDVI.

Analysis of the dynamics of African vegetation using the normalized difference vegetation index
International Journal of Remote Sensing, 1986Images at a resolution of 8 km are currently being generated for the whole of Africa, displaying the normalized difference vegetation index (NDVI). These images have undergone a process of temporal compositing to reduce the effects of cloud cover and atmospheric variation.

Estimation of Crop Coefficients Based on Normalize Difference Vegetation Index
Journal of Agriculture Research and Technology, 2022Crop coefficient is one of the most important parameters used for the estimation of crop evapotranspiration (ETc). Crop coefficient (Kc)-based estimation of crop evapotranspiration is most commonly used methods for irrigation water management. However, crop coefficient approach used for estimation ETc using the generalized crop coefficients mentioned ...
