Relationship between the Growing Season Maximum Enhanced Vegetation Index and Climatic Factors on the Tibetan Plateau [PDF]

Remote Sensing, 2014
Temperature and water conditions affect vegetation growth dynamics and associated spectral measures. We examined the response of the growing season maximum enhanced vegetation index (MEVI) to the growing season temperature, precipitation, vapor pressure and relative humidity on the Tibetan Plateau.

Future changes in summer MODIS-based enhanced vegetation index for the South-Central United States

Ecological Informatics, 2017
Abstract Evaluating the response of vegetation to climate change is relevant to improving the management of both human and natural systems. Here, we quantify the response of the MODIS-based enhanced vegetation index (EVI) to temperature, precipitation, and large-scale natural variability across the South-Central U.S.

Influence of solar zenith angle on the enhanced vegetation index of a Guyanese rainforest

Remote Sensing Letters, 2015
In this study, the effect of solar zenith angle () on enhanced vegetation index (EVI) of a Guyanese tropical rainforest was studied. For this sub-crown resolution, hyperspectral data have been collected with an unmanned aerial vehicle (UAV) at five different solar zenith angles in a 1-day period.

Multiband drought index enhances soil and vegetation moisture monitoring

SPIE Newsroom, 2009
Drought, the most complex and least understood of all natural hazards, also affects more people than any other.1 Traditional drought monitoring is based on observations at specific locations, and thus lacks continuous spatial coverage. Satellite remote sensing offers an effective means to continuously monitor drought across wide areas.

Enhanced vegetation index using Moderate Resolution Imaging Spectroradiometers

2012 5th International Congress on Image and Signal Processing, 2012
The enhanced vegetation index (EVI) was developed as a standard satellite vegetation product for the Terra and Aqua Moderate Resolution Imaging Spectroradiometers (MODIS). In this paper, MOD3A3, a global dataset with 1km spatial resolution and one month temporal resolution, was selected as the data source. The dynamic changes of vegetation EVI in China

Assessing landscape changes in Laos using MODIS Enhanced Vegetation Index

The ongoing rapid and vast land cover and land use transformations in Laos are only documented by punctual local case studies; information on national level is barely available. We explore ways to address this by using MODIS vegetation index times series data to detect medium to large scale transformation on the national level.
