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.
Syntax
GAGetModelParameter_ga (in_ga_model_source, model_param_xpath)
| Parameter | Explanation | Data Type |
in_ga_model_source | The geostatistical model source to be analyzed. | File; Geostatistical Layer |
model_param_xpath | XML path to the required model parameter. | String |
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']"
# Check out the ArcGIS Geostatistical Analyst extension license
arcpy.CheckOutExtension("GeoStats")
# Execute GAGetModelParameter
outParam = arcpy.GAGetModelParameter_ga(modelSource, xmlPath)
# Show results
print outParam
