Why Normalized Difference Vegetation Index (NDVI)?
2022Plants play a very important role in ecological systems -- they transform CO2 into oxygen. It is therefore very important to be able to estimate the overall amount of live green vegetation in a given area. The most efficient way to provide such a global analysis is to use remote sensing, i.e., multi-spectral photos taken from satellites, drones, planes,

Temporal influences on normalized difference vegetation index
Proceedings of SPIE, 2008Normalized difference vegetation index (NDVI) is defined as a ratio of the difference of the infrared and red bands to the sum of the two bands. It can be estimated directly from satellite data, and has been widely used in numerous environmental studies. Yet the satellite-based NDVI was criticized for its variations with temporal factors (e.g.

Trend of normalized difference vegetation index (NDVI) over Turkey
Remote Sensing for Agriculture, Ecosystems, and Hydrology XX, 2018Ecosystem productivity, biome distribution, and forest carbon stocks are likely to be changed by the climate change. These ecosystems changes can be identified using Satellite based normalized difference vegetation index (NDVI). In this study, global inventory modeling and mapping studies (GIMMS) NDVI data acquired by the advanced very highresolution ...

Forecasting of the normalized difference vegetation index time series in Jbeniana
2018 4th International Conference on Advanced Technologies for Signal and Image Processing (ATSIP), 2018This paper deals with the study of the vegetation cover variation through the Normalized Difference Vegetation Index (NDVI) in the area of Jbeniana (Sfax, Tunisia). For this purpose, we use the images given by Sentinel-2. This allows us to present the time series of NDVI.

Analysis of the dynamics of African vegetation using the normalized difference vegetation index
International Journal of Remote Sensing, 1986Images at a resolution of 8 km are currently being generated for the whole of Africa, displaying the normalized difference vegetation index (NDVI). These images have undergone a process of temporal compositing to reduce the effects of cloud cover and atmospheric variation.

Estimation of Crop Coefficients Based on Normalize Difference Vegetation Index
Journal of Agriculture Research and Technology, 2022Crop coefficient is one of the most important parameters used for the estimation of crop evapotranspiration (ETc). Crop coefficient (Kc)-based estimation of crop evapotranspiration is most commonly used methods for irrigation water management. However, crop coefficient approach used for estimation ETc using the generalized crop coefficients mentioned ...

Upscale integration of normalized difference vegetation index: the problem of spatial heterogeneity
IEEE Transactions on Geoscience and Remote Sensing, 1992The correspondence between the normalized difference vegetation index (NDVI) calculated from average reflectances, M/sub NDVI/, and NDVI integrated from individual NDVIs, I/sub NDVI/, by simulating AVHRR data from high spatial resolution SPOT 1 Haute Resolution Visible radiometer and Landsat Thematic Mapper data is analyzed.

A simple equation relating the Microwave Polarization Difference Index (MPDI) and the Normalized Difference Vegetation Index (NDVI) is proposed which represents well data obtained from Nimbus 7/SMMR at 37 GHz and NOAA/AVHRR Channels 1 and 2. It is found that there is a limit which is characteristic of a particular type of cover for which both indices ...

Infrared Normalized Difference Vegetation Index for Sentinel-2A Imagery
2020 17th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2020Normalized Difference Vegetation Index (NDVI) is widely applied in several applications. It can be used to classify or identify the land coverage. However, the haze and cloud often disturb the accuracy of this value, which decreases the application performance.
