Inverse distance weight interpolator.

Class Hierarchy

Base classes

QgsInterpolator

Interface class for interpolations.

Methods

distanceCoefficient	Returns the distance coefficient, the parameter that sets how the values are weighted with distance.
setDistanceCoefficient	Sets the distance coefficient, the parameter that sets how the values are weighted with distance.

class qgis.analysis.QgsIDWInterpolator

Bases: QgsInterpolator

__init__(layerData: Iterable[QgsInterpolator.LayerData])

Constructor for QgsIDWInterpolator, with the specified layerData sources.

Parameters:

layerData (Iterable[QgsInterpolator.LayerData])

__init__(a0: QgsIDWInterpolator)

Parameters:

a0 (QgsIDWInterpolator)

distanceCoefficient(self) → float

Returns the distance coefficient, the parameter that sets how the values are weighted with distance. Smaller values mean sharper peaks at the data points. The default is a coefficient of 2.

Point values are weighted by 1 / ( distance ^ coefficient ).

Return type:

float

setDistanceCoefficient(self, coefficient: float)

Sets the distance coefficient, the parameter that sets how the values are weighted with distance. Smaller values mean sharper peaks at the data points.

Point values are weighted by 1 / ( distance ^ coefficient ).
