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.
| Parameter | Overview |
|---|---|
output_original_raster | boolean / required If true, the output of the original reflectance raster file is supplied ain addition to the NDVI image. The default value is false. |
Compatibility
