Disponible avec une licence Geostatistical Analyst.
Résumé
Uses the interpolation model in a geostatistical layer to predict a value at a single location.
Utilisation
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.
Syntaxe

Exemple de code
GACalculateZValue (Python window)
Predict a value at a location using a kriging geostatistical layer.

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

# Name: CalculateZValue_Example_02.py
# Description: Uses the interpolation model in a geostatistical
# layer to predict a value at a single location.
# Requirements: Geostatistical Analyst Extension
# Import system modules
import arcpy
# Set environment settings
arcpy.env.workspace = "C:/gapyexamples/data"
# Set local variables
inGALayer = "C:/gapyexamples/data/Kriging.lyr"
pointCoord = "-2000000 -50000"
# Check out the ArcGIS Geostatistical Analyst extension license
arcpy.CheckOutExtension("GeoStats")
# Execute CalculateZValue
outCZV = arcpy.GACalculateZValue_ga(inGALayer, pointCoord)
# Print results
print outCZV
