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 = (100*(NIR - RedEdge) - 10*(NIR - 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 |
| Data Type | Explanation |
| Raster | The output raster with the RTVICore index values. |
