Normalized Difference Vegetation Index

Definition of Normalized Difference Vegetation Index (NDVI)

The 'NDVI' product is derived from processing MOD13A1 Vegetation Indices 16-Day L3 Global time series available from 2000 to present. Vegetation indices have a long history of use over a wide range of applications, such as vegetation monitoring; climate and hydrologic modelling; agricultural activities; drought studies; etc.

Represented range

NDVI (average): -1.0/ 1.0

NDVI (change)

NDVI (anomalies)

Description

Average NDVI for the years (2017-2019).

Value difference (2001-2019).

Annual NDVI anomaly which is the NDVI average for the whole period (2000-2017) comparing it to the average NDVI of the year 2013-2017. The anomalies map shows the percentage deviation (per pixel) between 2013-2017 and the average for the whole region 2000-2017.
