Calculate Z-value

Available with Geostatistical Analyst license.

Summary

Uses the interpolation model in a geostatistical layer to predict a value at a single location.

Usage

  • This tool is generally used only in a model or in scripting.

Syntax

GACalculateZValue_ga (in_geostat_layer, point_coord)
ParameterExplanationData Type
in_geostat_layer

The geostatistical layer to be analyzed.

Geostatistical Layer
point_coord

The x,y coordinate of the point for which the Z-value will be calculated.

Point

Code sample

GACalculateZValue (Python window)

Predict a value at a location using a kriging geostatistical layer.

import arcpy
arcpy.env.workspace = "C:/gapyexamples/data"
outCZV = arcpy.GACalculateZValue_ga("C:/gapyexamples/data/Kriging.lyr", 
                                    "-2000000 -50000")
print(outCZV)
GACalculateZValue (stand-alone script)
