Fits a smooth surface that is defined by a mathematical function (a polynomial) to the input sample points.
Fits a smooth surface that is defined by a mathematical function (a polynomial) to the input sample points.
The result from this tool is a smooth surface that represents gradual trends in the surface over the area of interest.
The Local Polynomial Interpolation tool should be used when shortrange variation exists in the data.
Parameter  Explanation  Data Type 
in_features

The input point features containing the zvalues to be interpolated. 
Feature Layer 
z_field

Field that holds a height or magnitude value for each point. This can be a numeric field or the Shape field if the input features contain zvalues or mvalues. 
Field 
out_ga_layer
(Optional)

The geostatistical layer produced. This layer is required output only if no output raster is requested. 
Geostatistical Layer 
out_raster
(Optional)

The output raster. This raster is required output only if no output geostatistical layer is requested. 
Raster Dataset 
cell_size
(Optional)

The cell size at which the output raster will be created. This value can be explicitly set under Raster Analysis from the Environment Settings. If not set, it is the shorter of the width or the height of the extent of the input point features, in the input spatial reference, divided by 250. 
Analysis Cell Size 
power
(Optional)

The order of the polynomial. 
Long 
weight_field
(Optional)

Used to emphasize an observation. The larger the weight, the more impact it has on the prediction. For coincident observations, assign the largest weight to the most reliable measurement.
