NDVI Raster Function

The NDVI raster function can be used to detect vegetation cover in a raster image.

Overview

The normalized difference vegetation index (NDVI) is a standardized index allowing you to generate an image estimating a number of vegetation properties such as Leaf Area Index, biomass, chlorophyll concentration in leaves, plant productivity, fractional vegetation cover, and more. This index takes advantage of the contrast of characteristics between two bands from a multispectral raster dataset—the chlorophyll pigment absorption in the red band and the high reflectivity of plant material in the near-infrared (NIR) band.

For more information about the NDVI Raster Function, see NDVI function in ArcGIS Pro.

Parameters

ParameterDescription

Raster

The input multispectral raster.

Visible Band ID

Specifies the band ID that represents the red part of the electromagnetic spectrum.

Infrared Band ID

Specifies the band ID that represents the near-infrared part of the electromagnetic spectrum.

Scientific Output

The output values will range from -1.0 to 1.0, which is used in many scientific applications.
