Description

Definition

Normalized Difference Vegetation Index (NDVI) is a measure of the “greenness,” the relative density and health of vegetation, of the earth’s surface. The values range from -1 and +1. Values greater than .1 generally denote increasing degrees in the greenness and intensity of vegetation. Values between 0 and .1 are commonly characteristic of rocks and bare soil, and values less than 0 sometimes indicate clouds, rain, and snow.
