Output Z Domain (Environment setting)
Tools that honor the Output Z Domain environment will generate output datasets with the specified z-domain.
This environment allows the overriding of the default output spatial reference's z-domain. For a description of how the default z-domain is calculated, see Spatial reference and geoprocessing.
Usage notes
If the output is in a feature dataset, the environment will be ignored, as all geodatasets in a feature dataset automatically have the same z-domain.
When both the Z Resolution environment and the Output Z Domain environment are set, the Z Resolution value is used as well as the Output Z Domain's minimum z-value.
It is recommended that you use the Z Resolution environment in conjunction with the Output Z Domain environment to avoid creating a dataset with extremely small resolution value. Extremely small resolution values can lead to a deterioration of performance and additional storage requirements.
Dialog syntax
Same as Input—Use the default z-domain (calculated based on the input).
As Specified Below—Use the following fields to specify the valid z-coordinate range:
Min Z—Minimum z-value
Max Z—Maximum z-value
Python syntax
arcpy.env.ZDomain = "zMin zMax"
| Name | Explanation |
|---|---|
|
zMin |
The minimum z-value. |
|
zMax |
The maximum z-value. |
Scripting syntax
import arcpy
# Set the Z Domain to a minimum of 0 and a maximum of 25000
arcpy.env.ZDomain = "0 25000"
