NDVI

Description

A processing block that computes the Normalized Difference Vegetation Index (NDVI).

See this block on the marketplace.

How it works

NDVI is used as an indicator for vegetation health, and it's computed via the following formula:

Input bands are of data type unsigned integer, while the output is of type float. All metadata elements provided by the input dataset as properties are propagated to the output tiles.
