The first and last pulse data and the normalized difference vegetation index are used in the process.

Remote Sensing from satellite and airborne platforms provides images depicting vineyard conditions, for example vine productivity from normalized difference vegetation index (NDVI).

MSC - Meteorological Service of Canada NDVI - Normalized Difference Vegetation Index.

Scientists use that information to calculate the Normalized Difference Vegetation Index (NDVI), an indicator of photosynthetic activity or "greenness" of the landscape.

The most successful of these approaches is based on tracking the temporal change of a Vegetation Index (like Normalized Difference Vegetation Index(NDVI)).

FAPAR can also be used as an indicator of the state and evolution of the vegetation cover; with this function, it advantageously replaces the Normalized Difference Vegetation Index (NDVI), provided it is itself properly estimated.

Whereas the Normalized Difference Vegetation Index (NDVI) is chlorophyll sensitive, the EVI is more responsive to canopy structural variations, including leaf area index (LAI), canopy type, plant physiognomy, and canopy architecture.

Using satellite-derived estimates of the Normalized Difference Vegetation Index (NDVI) for terrestrial habitats and sea-surface chlorophyll for the oceans, it is estimated that the total (photoautotrophic) primary production for the Earth was 104.9 Gt C yr.

Another difference between Normalized Difference Vegetation Index and EVI is that in the presence of snow, Normalized Difference Vegetation Index decreases, while EVI increases (Huete, 2002).
