Error when creating some WGS 1984 UTM spatial references

Tim_McGinnes — Fri, 07 May 2021 05:53:07 GMT

Arcpy in ArcGIS Pro 2.7.3 is giving errors when trying to create a spatial reference. It is happening with single digit WGS 1984 UTM Zones. Code to replicate below:

sr = arcpy.SpatialReference("WGS 1984 UTM Zone 10N") print(sr.name) WGS_1984_UTM_Zone_10N sr = arcpy.SpatialReference("WGS 1984 UTM Zone 6S") Traceback (most recent call last): File "<string>", line 1, in <module> File "C:\Program Files\ArcGIS\Pro\Resources\ArcPy\arcpy\arcobjects\mixins.py", line 942, in __init__ self._arc_object.createFromFile(item, vcs) RuntimeError: ERROR 999999: Something unexpected caused the tool to fail. Contact Esri Technical Support (http://esriurl.com/support) to Report a Bug, and refer to the error help for potential solutions or workarounds.

You might try two spaces between Zone and 6S. I ran into a similar problem with Desktop, and the extra space was the fix. I think the extra space is used for aligning single and double digits.

>>> sr = arcpy.SpatialReference("WGS 1984 UTM Zone 10N") >>> print sr.name WGS_1984_UTM_Zone_10N >>> sr = arcpy.SpatialReference("WGS 1984 UTM Zone 6S") # single space Runtime error Traceback (most recent call last): File "<string>", line 1, in <module> File "c:\program files (x86)\arcgis\desktop10.5\arcpy\arcpy\arcobjects\mixins.py", line 992, in __init__ self._arc_object.createFromFile(item, vcs) RuntimeError: ERROR 999999: Error executing function. >>> sr = arcpy.SpatialReference("WGS 1984 UTM Zone 6S") # double space >>> print sr.name WGS_1984_UTM_Zone_6S

Yes. I found the same.

The cause lies with the list of names of coordinate systems for ArcGIS Pro.

Same with ArcMap as well.
