Output M Domain (Environment setting)

Tools that honor the Output M Domain environment will generate output datasets with the specified measure (m)-domain.

Usage notes

Dialog syntax

Scripting syntax

arcpy.env.MDomain = "mMin mMax"



"mMin mMax"

  • mMin—Minimum m-value.
  • mMax—Maximum m-value.

Setting the m-domain to an empty string will default to using the m-domain from input data.

MDomain syntax
import arcpy

# Set the MResolution first
arcpy.env.MResolution = 0.0001 

# Then set the MDomain (only the origin will be used when the resolution is set)
arcpy.env.MDomain = "0 10000000"
