Long term trend analysis of vegetation dynamics over Rajasthan using satellite derived enhanced vegetation index

Journal of Agrometeorology, 2023
Enhanced Vegetation Index (EVI) time series data from the Moderate Resolution Imaging Spectroradiometer (MODIS) for the years 2001 to 2021 were used to understand the vegetation dynamics in the Rajasthan during last 21 years.

Multifractal Analysis of MODIS Aqua and Terra Satellite Time Series of Normalized Difference Vegetation Index and Enhanced Vegetation Index of Sites Affected by Wildfires. [PDF]

Entropy (Basel), 2022
The MODIS Aqua and Terra Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) time series acquired during nearly two decades (2000 to 2020) covering the area burned by the Camp Fire (California) in 2018 is investigated in this study by using the multifractal detrended fluctuation analysis in relation to the recovery process

Analysis of Differences in Phenology Extracted from the Enhanced Vegetation Index and the Leaf Area Index. [PDF]

Sensors (Basel), 2017
Remote-sensing phenology detection can compensate for deficiencies in field observations and has the advantage of capturing the continuous expression of phenology on a large scale. However, there is some variability in the results of remote-sensing phenology detection derived from different vegetation parameters in satellite time-series data. Since the

Spatial Enhancement of Modis Leaf Area Index Using Regression Analysis with Landsat Vegetation Index [PDF]

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
The Leaf Area Index (LAI) is an important indicator of vegetation development which can be used as an input parameter in hydrological and biochemical models (e.g. crop models for yield prediction and forecast) and is, thus, relevant information to monitor food production and to feed an early warning system for famine crisis.

Satellite monitoring of vegetation dynamics: Sensitivity enhancement by the wide dynamic range vegetation index [PDF]

Geophysical Research Letters, 2004
Synoptic monitoring of vegetation dynamics relies on satellite observations of the distinctive spectral contrast between red and near infrared reflectance that photosynthetically active green vegetation exhibits. It has long been recognized that the Normalized Difference Vegetation Index (NDVI) suffers a rapid decrease of sensitivity at moderate‐to ...

Monitoring vegetation dynamics using multi-temporal Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) images of Tamil Nadu

Journal of Applied and Natural Science, 2023
Vegetation indices serve as an essential tool in monitoring variations in vegetation. The vegetation indices used often, viz., normalized difference vegetation index (NDVI) and enhanced vegetation index (EVI) were computed from MODIS vegetation index products.

Fire Recurrence and the Dynamics of the Enhanced Vegetation Index in a Mediterranean Ecosystem

International Journal of Applied Geospatial Research, 2015
This study area is located in the eastern littoral of the Iberian Peninsula; its importance resides in its Mediterranean ecosystem, complex topography, extensive land use changes, and intensive forest fires history. The study is done at the landscape level, covering a wide area for an extended period of time.

The use of Enhanced Vegetation Index for assessing access to different types of green space in epidemiological studies. [PDF]

J Expo Sci Environ Epidemiol
Abstract Background Exposure to green space can protect against poor health through a variety of mechanisms. However, there is heterogeneity in methodological approaches to exposure assessments which makes creating effective policy recommendations challenging.
