Tools that honor this environment will apply the M resolution to output geodatasets.
For a description of the default M resolution, see the following topic: Spatial reference and geoprocessing.
- The M Resolution (unlike XY Resolution and Z Resolution environments) of geodatasets created inside a feature dataset is not constrained to match the feature dataset's M resolution.
- If the M Resolution environment is not set, tools such as Create Feature Class, Create Feature Dataset, and Create Raster Catalog will set the default M resolution at 0.0001.
M Resolution—The M resolution to be set on the output geodatasets. Set this environment if the default M resolution is inadequate.
arcpy.env.MResolution = double
Sets the M resolution to be used on output geodatasets. The M resolution, expressed as a very small distance, refers to the number of significant digits used to store M values.
import arcpy # Set the MResolution environment to a double arcpy.env.MResolution = 0.002
