QgsInterpolator

Interface class for interpolations.

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 ).
