SearchNeighborhoodSmoothCircular (arcpy)

Resumen

The SearchNeighborhoodSmoothCircular class can be used to define the search neighborhood for Empirical Bayesian Kriging, IDW, Local Polynomial Interpolation, and Radial Basis Functions (only when the INVERSE_MULTIQUADRIC_FUNCTION keyword is used). The class accepts inputs for the radius of the searching circle and a smoothing factor.

Sintaxis

SearchNeighborhoodSmoothCircular ({radius}, {smoothFactor})
ParámetroExplicaciónTipo de datos
radius

The distance, in map units, specifying the length of the radius of the searching circle.

Double
smoothFactor

Determines how much smoothing will be performed. 0 is no smoothing; 1 is the maximum amount of smoothing.
