Calculate Z-value (Geostatisical Analyst)

Récapitulatif

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 because the ArcMap Identify tool can also be used to calculate the predicted value at a single location.

Syntaxe

GACalculateZValue_ga (in_geostat_layer, point_coord)

Paramètre	Explication	Type de données
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

Exemple de code

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)

# 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
