Comparison of time-integrated NDVI and annual maximum NDVI for assessing grassland dynamics
Ecological Indicators, 2022 The saturation of NDVI makes the annual maximum NDVI(NDVImax) underestimate vegetation with high coverage. Time-Integrated NDVI(TI-NDVI) accumulates NDVIs of vegetation at different growing stages in one growing season. TI-NDVI might alleviate the saturation effect of NDVImax when vegetation dynamics are assessed at annual time scale.

NDVI Computation from Hyperspectral Images
2023 13th Workshop on Hyperspectral Imaging and Signal Processing: Evolution in Remote Sensing (WHISPERS), 2023Agriculture has witnessed a series technological transformations over time. In recent years, multispectral and hyperspectral satellites have become powerful tools in precision and efficient agricultural practices. Given the richness of information they provide and the fact that multi- and hyperspectral data are not easy to interpret, a consistent ...

Global correlation analysis for NDVI and climatic variables and NDVI trends: 1982-1990
International Journal of Remote Sensing, 2002The relationship between the Normalized Difference Vegetation Index (NDVI) and climatic variables was analysed on a global scale using the Pathfinder AVHRR Land NDVI data set, and observed climate data for the period 1982-1990. A significant correlation between interannual NDVI and temperature variation was recognized in the northern mid- to high ...

Yukon River Discharge-NDVI Relationship
2020Similar to the Mackenzie River, a strong seasonal consistency between NDVI and discharge exists for Yukon River. The flow-NDVI association is particularly strong before June, discharge rapidly rises and reaches the peak the 1st half of June, while the NDVI in the period of April to June increases fastest and reaches the maximum in July.

Sensor intercalibration - adjustment of MODIS-NDVI-to NOAA-AVHRR-NDVI data
IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004The Normalized Difference Vegetation Index (NDVI) is the most often used vegetation index to study environmental change. Usually, NOAA-Advanced Very High Resolution Radiometer (AVHRR)-data are used to calculate the NDVI, because these data are available for more than 20 years. Today, data with an improved quality like the one of EOS-Moderate Resolution

Mapping precipitation-corrected NDVI trends across Namibia
Science of The Total Environment, 2019Savannas comprise a major component of the Earth system and contribute ecosystem services and functions essential to human livelihoods. Monitoring spatial and temporal trends in savanna vegetation and understanding change drivers is therefore crucial. Widespread greening has been identified across southern Africa; yet its drivers and manifestations on ...
