Output M Domain (Environment setting)
Tools that honor the Output M Domain environment will generate output datasets with the specified measure domain (m-domain).
Usage notes
Unlike x,y and z-domains, the m-domain of a feature class in a feature dataset is not constrained to match the feature dataset's m-domain. Feature classes created in a feature dataset will get their m-domain from the Output M Domain environment, not from the feature dataset.
If the M Resolution environment is set as well as the Output M Domain environment, the resolution value is used in combination with the domain's minimum value.
It is recommended that you use the M Resolution environment in conjunction with the Output M Domain environment to avoid creating a dataset with extremely small resolution value. Extremely small resolution values can cause poor performance of the software when the data is used.
Dialog syntax
Same as Input—Use the m-domain from input data.
As Specified Below—Use the following fields to specify the domain range:
Min M—Minimum m-value
Max M—Maximum m-value
Python syntax
arcpy.env.MDomain = "mMin mMax"
| Name | Explanation |
|---|---|
|
mMin |
The minimum m-value. |
|
mMax |
The maximum m-value. |
Scripting 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"
