A Normalized Difference Vegetation Index (NDVI) Time-Series of Idle Agriculture Lands: A Preliminary Study [PDF]

open access: yesEngineering Journal, 2011
In this paper, the NDVI time-series collected from the study area between year 2003 and 2005 of all land cover types are plotted and compared. The study area is the agricultural zones in Banphai District, Khonkean, Thailand. The LANDSAT satellite images of different dates were first transformed into a time series of Normalized Difference Vegetation ...

Estimation of the Normalized Difference Vegetation Index (NDVI) Variation for Selected Regions in Iraq for two Years 1990 & 2001 [PDF]

open access: yesمجلة جامعة الانبار للعلوم الصرفة, 2012
The Normalized Difference Vegetation Index (NDVI) is commonly used as a measure of land surface greenness based on the assumption that NDVI value is positively proportional to the amount of green vegetation in an image pixel area.

The Normalized Difference Vegetation Index (NDVI): unforeseen successes in animal ecology [PDF]

open access: yesClimate Research, 2011
This review highlights the latest developments associated with the use of the Normal- ized Difference Vegetation Index (NDVI) in ecology. Over the last decade, the NDVI has proven extremely useful in predicting herbivore and non-herbivore distribution, abundance and life history traits in space and time.

Drought monitoring over India through Normalized Difference Vegetation Index (NDVI) [PDF]

open access: yesMAUSAM, 2010
Normalized Difference Vegetation Index (NDVI) is a simple index to monitor the state of vegetation (stressed/unstressed) which can be derived from satellite data. Hence an attempt is made to find out the vegetation responses to rainfall through NDVI over the study area.
