pvi

eolab.georastertools.processing.algo.pvi(bands: ndarray) → ndarray

Compute the Perpendicular Vegetation Index The coefficient ranges from -1 to 1 in each pixel.

The function considers the bands of the input data in the following order : Red, NIR (Near Infra-Red).

\[PVI = 0.74 (NIR - 0.90893 RED - 7.46216)\]

Parameters:

input_data (np.ndarray) – Numpy array of 3 dimensions (number of bands, number of lines, number of columns) with number of bands > 1.

Returns:

Numpy array of the size (number of lines, number of columns) containing the computed PVI.
