Get Model Parameter (Geostatistical Analyst)

Available with Geostatistical Analyst license.

Summary

Gets model parameter value from an existing geostatistical model source.

Usage

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

• The geostatistical model source must be a geostatistical layer.

• See Set Model Parameter for additional information.

• An example input model source:

  /model[@name = 'Kriging']/model[@name = 'Variogram']/value[@name = 'Nugget']; /model[@name = 'Kriging']/model[@name = 'Variogram']/model[@name = 'VariogramModel']/value[@name = 'Range']

  will return "out_param_value" = 0.345;1127.14

• The returned value can be viewed in the Geoprocessing History item for the run of this tool.

Code sample

GetModelParameter example 1 (Python window)

Extract parameter values from a geostatistical model source.

import arcpy
arcpy.env.workspace = "C:/gapyexamples/data"
outParam = arcpy.GAGetModelParameter_ga(
    "C:/gapyexamples/data/kriging.lyr",
    "/model[@name = 'Kriging']/model[@name = 'Variogram']/value[@name = 'Nugget']")
print(outParam)

GetModelParameter example 2 (stand-alone script)

Extract parameter values from a geostatistical model source.

# Name: GAGetModelParameter_Example_02.py
# Description: Gets model parameter value from an existing geostatistical
#              model source.
# Requirements: Geostatistical Analyst Extension

# Import system modules
import arcpy

# Set environment settings
arcpy.env.workspace = "C:/gapyexamples/data"

# Set local variables
modelSource = "C:/gapyexamples/data/kriging.lyr"
xmlPath = "/model[@name = 'Kriging']/model[@name = 'Variogram']/value[@name = 'Nugget']"

# Execute GAGetModelParameter
outParam = arcpy.GAGetModelParameter_ga(modelSource, xmlPath)

# Show results
print(outParam)
