ArcMap

Calculate Z-value

Mit der Geostatistical Analyst-Lizenz verfügbar.

Zusammenfassung

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

Verwendung

  • 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

arcpy.ga.GACalculateZValue(in_geostat_layer, point_coord)
ParameterErklärungDatentyp
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

NameErklärungDatentyp
out_z_value

The predicted Z-value at the specified x,y coordinate.

Double

Codebeispiel

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.

# 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
