Set Model Parameter (Geostatistical Analyst)

Geostatistical Analyst のライセンスで利用可能。

サマリー

Sets parameter values in an existing geostatistical model source.

使用法

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

• The geostatistical model source must be a geostatistical layer.

• The examples below can be used in the Parameter XML Path to specify which parameter will be set to a new value.

  • To change the number of lags parameter:

    /model[@name = 'Kriging']/model[@name = 'Variogram']/value[@name = 'NumberOfLags']

  • To change the weight parameter for LPI:

    /model[@name = 'LPI']/value[@name = 'Weight']

  • To specify whether the nugget should be recalculated in Kriging:

    /model[@name = "Kriging"]/model[@name = "Variogram"]/value[@name = "Nugget"]/@auto

    Then specify a true or false value (true implies that a new nugget value will be calculated when the XML file is used).

  • To specify whether a new range should be calculated:

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

    Then specify a true or false value (true implies that a new range value will be calculated when the XML file is used).

  • To specify a new nugget value:

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

• The XPath code snippet below sets multiple parameters via a single call to the tool.

  params = "/model[@name = 'Kriging']/model[@name = 'Variogram']/value[@name = 'Nugget']/@auto;\
  
            /model[@name = 'Kriging']/model[@name = 'Variogram']/model[@name = 'VariogramModel']/value[@name = 'Range'];\
  
            /model[@name = 'Kriging']/model[@name = 'Variogram']/model[@name = 'VariogramModel']/value[@name = 'Sill']"
  
  vals = "true;5.5;777"
  
  gp.GASetModelParameter_ga(inXMLFile, params, vals, outXMLFile)

コードのサンプル

SetModelParameter example 1 (Python window)

Change the value of a parameter in a geostatistical model source.

import arcpy
from arcpy import env
env.workspace = "C:/gapyexamples/data"
newParam = arcpy.GASetModelParameter_ga(
    "C:/gapyexamples/data/kriging.lyr", 
    "/model[@name = 'Kriging']/model[@name = 'Variogram']/value[@name = 'Nugget']",
    "1", "C:/gapyexamples/output/outModel.xml")
print(newParam)

SetModelParameter example 2 (stand-alone script)

Change the value of a parameter in a geostatistical model source.

# Name: GASetModelParameter_Example_02.py
# Description: Sets parameter value in 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']"
newValue = 1
outModel = "C:/gapyexamples/output/outModel.xml"

# Execute GASetModelParameter
newParam = arcpy.GASetModelParameter_ga(modelSource, xmlPath, newValue, outModel)

# Show results
print(newParam)
