Get Model Parameter

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 is either a geostatistical layer or a geostatistical model (XML).

  • 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 view in the Results window.

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)
