ConvertMValueUnitsOfMeasure example 1 (Python window)
The following script demonstrates how to use the ConvertMValueUnitsOfMeasure function in immediate mode.
# Name: ConvertM-ValueUnitsOfMeasure_arcmap.py
# Description: Converts the measure (m) values of a dataset from one unit to another. The m-values of the input dataset are modified upon executing this tool.
# Import arcpy module
import arcpy
# tool variables
in_network = "network_lyr"
in_source_unit_of_measure = "feet"
in_target_unit_of_measure = "miles"
in_precision = "3"
# set current workspace
arcpy.env.workspace="C:/Data/NY_Data.gdb/LRSN_MilePoint"
# execute the tool
arcpy.ConvertMValueUnitsOfMeasure_locref(in_network, in_source_unit_of_measure, in_target_unit_of_measure, in_precision)
ConvertMValueUnitsOfMeasure example 2 (stand-alone script)
The following script demonstrates how to use ConvertMValueUnitsOfMeasure in a stand-alone Python script.
# Name: ConvertM-ValueUnitsOfMeasure.py
# Description: Converts the measure (m) values of a dataset from one unit to another. The m-values of the input dataset are modified upon executing this tool.
# Import arcpy module
import arcpy
# Check out any necessary licenses
arcpy.CheckOutExtension("Highways")
# Local variables:
network = r"C:/Data/NY_Data.gdb/LRSN_MilePoint"
# Make a feature layer for network
arcpy.MakeFeatureLayer_management(network, "network_lyr")
# Process: Convert M-value Units Of Measure
arcpy.ConvertMValueUnitsOfMeasure_locref("network_lyr", "Feet", "Miles", "3")
