geowombat.evi(data, nodata=None, mask=False, sensor=None, scale_factor=None)#

Calculates the enhanced vegetation index

Parameters:

data (DataArray) – The xarray.DataArray to process.
nodata (Optional[int or float]) – A ‘no data’ value to fill NAs with. If None, the ‘no data’ value is taken from the xarray.DataArray attributes.
mask (Optional[bool]) – Whether to mask the results.
sensor (Optional[str]) – The data’s sensor. If None, the band names should reflect the index being calculated.
scale_factor (Optional[float]) – A scale factor to apply to the data. If None, the scale value is taken from the xarray.DataArray attributes.

Equation:

\[EVI = 2.5 \times \frac{NIR - red}{NIR + 6 \times red - 7.5 \times blue + 1}\]
