NDVI Variability in North East India

Scottish Geographical Journal, 2009
Abstract The variability of the Normalized Difference Vegetation Index (NDVI) in north east India in response to rainfall and temperature was analysed using twice-monthly NOAA/AVHRR satellite imagery acquired during 1982–2002 from the GIMMS (Global Inventory Modeling and Mapping Studies) data-set.

Recommendations for Future Application of NDVI

2015
As discussed in the Introduction, both the UNCCD and the GEF use land cover to monitor land degradation. The UNCCD progress indicators (formerly known as impact indicators) should show progress made in achieving long-term benefits for people living in areas affected by desertification, land degradation, and drought, for affected ecosystems, and for the

Determining Cover Percentage Using NDVI Sensors

2022
In drip irrigation, one of the most important parameters in determining the correct amount of irrigation water is the percentage of plants cover. Keeping the cover percentage constant throughout the growing period may cause more irrigation than the plants need, especially in the vegetative growth stages of plants.

Алгоритм оценки долговременных вариаций MODIS NDVI

2018
An algorithm was developed for assessment of long-term variations of vegetation characteristics. The algorithm use NDVI data from spectroradiometer MODIS of Terra and Aqua satellites. The algorithm includes pre-processing procedures – the restoration of missing values, smoothing using Savitsky-Golay filter.
