scale#
- scale(array: ndarray | MaskedArray, perc: int = 2) ndarray | MaskedArray[source]#
Scale a raster given as a np.ndarray between 0 and 1.
The min max are computed with percentiles (2 by default), but can be true min/max if
perc=0.Warning
If 3D, the raster should be in rasterio’s convention:
(count, height, width)- Parameters:
array (AnyNumpyArray) – Matrix to be scaled
perc (int) – Percentile to cut. 0 = min/max, 2 by default
- Returns:
Scaled matrix
- Return type:
numpy array
