xrspatial.mcda.combine.wpm

xrspatial.mcda.combine.wpm(criteria: Dataset, weights: dict[str, float], name: str = 'wpm') → DataArray

Weighted Product Model.

Multiplicative combination: per-pixel product(x_i ^ w_i). More sensitive to low scores than WLC.

Parameters:

• criteria (xr.Dataset) – Standardized criterion layers (0-1).

• weights (dict) – {criterion_name: weight}, must sum to ~1.0.

• name (str) – Name of the output DataArray.

Returns:

Composite suitability surface.

Return type:

xr.DataArray
