index

Computes an index from the bands of an input raster. In addition to the indices ‘ndvi’, ‘evi’, ‘msavi’, ‘ndre’, ‘reci’, ‘ndmi’, ‘methane’ and ‘pri’ all indices in https://github.com/awesome-spectral-indices/awesome-spectral-indices are available (depending on the bands available on the corresponding satellite product).

Sources

raster: Input raster.

Sinks

index_raster: Single-band raster with the computed index.

Parameters

index: The choice of index to be computed (‘ndvi’, ‘evi’, ‘msavi’, ‘ndre’, ‘reci’, ‘ndmi’, ‘methane’, ‘pri’ or any of the awesome-spectral-indices).

Tasks

compute_index: Computes index over the input raster.
