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. In ArcMap, the Identify tool can also be used to calculate the predicted value at a single location.
Syntax
GACalculateZValue_ga (in_geostat_layer, point_coord)
| Parameter | Explanation | Data 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)
Predict a value at a location using a kriging geostatistical layer.

# layer to predict a value at a single location.
# Requirements: Geostatistical Analyst Extension
# Import system modules
import arcpy
# Set environment settings

# Check out the ArcGIS Geostatistical Analyst extension license
arcpy.CheckOutExtension("GeoStats")
# Execute CalculateZValue
outCZV = arcpy.GACalculateZValue_ga(inGALayer, pointCoord)
# Print results
print outCZV
