RTVICore

Summary

Calculates the Red-Edge Triangulated Vegetation Index (RTVICore) from a multiband raster object and returns a raster object with the index values.

Discussion

The Red-Edge Triangulated Vegetation Index (RTVICore) method is a vegetation index for estimating leaf area index and biomass. This index uses reflectance in the NIR, red-edge, and green spectral bands.

\(RTVICore \space = \space (100 * (NIR \space - \space RedEdge) \space - \space 10 * (NIR \space - \space Green))\)

For information about other multiband raster indexes, see the Band Arithmetic raster function.

The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.

Syntax

RTVICore(raster, {nir_band_id}, {redEdge_band_id}, {green_band_id})

Parameter	Explanation	Data Type
raster	The input raster.	Raster
nir_band_id	The band ID of the near-infrared band. The ID index uses one-based indexing. The default value is 7.	Integer
redEdge_band_id	The band ID of the red-edge band. The band ID index uses one-based indexing. The default value is 6.	Integer
green_band_id	The band ID of the green band. The ID index uses one-based indexing. The default value is 3.	Integer

Return value

Data Type	Explanation
Raster	The output raster with the RTVICore index values.

Code sample

RTVICore example

Calculates the Red-Edge Triangulated Vegetation Index for a Sentinel-2 image.

import arcpy

RTVICore_raster = arcpy.sa.RTVICore("Sentinel2.tif",8,5,3)
