Splitting of polygons in ArcGIS Pro 2.3 changes my features and symbology

AdrianWelsh

I just upgraded to Pro 2.3 and am doing the exact same process I did in 2.2 but with different results (same day).

I have a polygon feature in a file geodatabase that is symbolized based on a domain I have set up.

When I use the Split tool to divide up my polygon, the new resulted split polygons change all my domains to null.

This is more of a potential bug report than anything else. But, has anyone else seen this?

There are so many "split" tools now, is it this one

http://pro.arcgis.com/en/pro-app/tool-reference/analysis/split.htm

which has this warning

Caution:

Geoprocessing tools do not honor geodatabase feature class or table field split policies.

Good question. For my splitting, it is the Split tool that is in my Edit ribbon

I do not have split policies set up (and didn't know they existed until you shared that article!). So, my feature class should behave as the "default value". The default value says:

Default value—The attributes of the two resulting features take on the default value for the attribute of the given feature class or subtype.

If there is not default value, I suppose that it must be "null".... That's rather a pain. I want my splitting to go back to how things were in 2.2 and prior, which is apparently "duplicate value"

Duplicate—The attribute of the two resulting features takes on a copy of the original object's attribute value.

Now, I guess I need to figure out where to set my splitting policies. I did not see how to do so in a quick glance in the Settings, so I'll keep looking around. But, I guess this is likely the answer

AdrianWelsh

duh, it's in my Domain settings.......

Weird. One weird change I'll have to always remember in 2.3.

Thanks Dan!

JuliaNoran1

So, do you suppose this change in domain settings from default to duplicate has to be made for use in all future versions of Pro? This is expected behavior and not a 2.3 bug?

AdrianWelsh

Julia,

Good question. I am going to tag Kory Kramer‌ on that since he might have a good answer.

hi,

here a script for update all your domain:

import arcpy

domains = arcpy.da.ListDomains(r"your connection.sde")

for domain in domains:
arcpy.management.AlterDomain(r"your connection.sde", format(domain.name), "", "", "Duplicate", "DEFAULT")

AdrianWelsh

Thanks Rémi! For projects with lots of domains, this is terrific!

I would also like to know if this is a bug and not to be the expected behavior in future versions.

Hi Matthew,

The behavior is expected since the Split tool will respect the split policy that is defined on the source geodatabase. This is mentioned in the documentation for the Split tool: Split a feature—ArcGIS Pro | ArcGIS Desktop

You can check the split policy by right-clicking on the layer in the Contents pane > Design > Domains. The Split Policy will be listed here. It sounds like your data could be set "Default", but perhaps you want to set it to "Duplicate".

Thanks,

Scott

MatthewDriscoll

Thanks. I guess my confusion is when I edit in ArcMap this behavior does not happen. Well I guess more importantly can we get a Cut tool for Pro? So if we have something like over 50 databases with hundreds of features now we have to go through them all and change every single one? Or do I only need to worry about the ones which have domains? This was not an issue with the Map Cut Tool. Split was only available in Map with an Advanced license and a majority of users used Polygon Cut as there main editing tool, which is not available in Pro I don't think.

It even looks like the Divide tool is constrained by the domain split policy. We need a tool which can Cut which does not have this constraint.

Apologies to everyone that knows the history of this in Pro, but coming from ArcMap, why would this complexity be added? It's a simple cut. Keep the values unless I changed it. I agree that duplicate should be "default".

MatthewDriscoll

They depreciated it for Split only, see this thread https://community.esri.com/thread/225070-ability-to-split-polygon-features-with-arcgis-pro-sdk . How ever if you go to the sdk editing concepts it still shows examples of cut and nothing about split https://github.com/esri/arcgis-pro-sdk/wiki/ProConcepts-Editing. So perhaps one can still write an add-in using cut as a work around? They should recreate a cut tool in Pro tool as it did not seem to be causing any problems.

Hi Scott Harris‌

I'm viewing an AGOL map containing AGOL hosted feature layers in ArcGIS pro (easier to do bulkier data transformations than AGOL tools).

I'm wanting to use the split tool on this however it had me confused (and embarrassed as I had someone watching me while I completed what I said was an 'easy task' but because my symbology is based on an attribute info the split would cause both polygons to dissapear).

I've gone to the Domain Split Policy as stated above and changed this to Duplicate. However it will not allow me to save the domain changes. The button is not greyed out (so it isn't the common problem of having unsaved edits to the features), it acts like it is applying the changes however in the background it just hasn't (button still coloured, I go to get out of the fields view and it mentions unsaved changes found, I click save all, the loop repeats).

Is there an easier way of going about this other than the usual two clicks for a split, the copying of a layer, changing its symbology and refilling the whole attribute table?

I reckon it would be great if this tool had buttons similar to the clip editor that asks if you want to preserve the attribute data.

Hi Naomi,

Domains for an ArcGIS Online hosted feature service are read-only in ArcGIS Pro - however, I believe they are not true domains once they are published to AGOL, meaning there is no split policy to modify.

Here is what I see when I attempt to modify the domain of an ArcGIS Online hosted feature service:

Also, when features are split the attributes should be copied to the newly split features. You should be able to verify this by using the attribute pane to check the attributes after splitting (you can have both panes open side-by-side).

Thanks,

Scott

Hi @Scott_Harris,

My attributes do not copy over to the newly split features anymore when using the split tool. This used to work for me, but I think it stopped since upgrading to 2.9. The domains are now read only for this workspace for hosted feature services. I believe I had them set to Duplicate, but now they are Default and I cannot change it. What can I do to fix this?

Scott_Harris

@LukeGilner1 If the split policy somehow changed on your hosted feature service without any intervention, that sounds like a bug. However, perhaps something changed on the client side (upgrading ArcGIS Pro)? My suggestion would be to work with Esri Technical Support to find a resolution. If you need the policy to be changed to duplicate, perhaps there is a way to do it using REST calls. The other option would be to download the data, change the split policy to what you need, and republish or overwrite the service.

-Scott

LukeGilner1

Scott - yes, this seems to have occurred after upgrading Pro to 2.9. I'm not savy enough to edit the REST calls. It wouldn't work well to republish because of all the replicas being used in Field Maps. I'll see if tech support can help, or I'll uninstall and reinstall an earlier version.

LukeGilner1

@Scott_Harris - I uninstalled ArcPro and reinstalled version 2.8, and no longer have the issue with the split policy. The domains are read only in this workspace for hosted features and the split policy is set to default, but the attributes do copy over to both split features as I want them to.

LukeGilner1

I did follow up with Tech Support on this, and he was able to reproduce the issue in 2.9, and found that the issue does not occur in 2.8. He has logged bug number: BUG-000148890.

Scott_Harris

@LukeGilner1 Thanks for following up. I made the team responsible for this area of the software aware of the newly logged defect as well.

RichSiko

Scott you mentioned in this thread "If you need the policy to be changed to duplicate, perhaps there is a way to do it using REST calls".

Can you or anyone else confirm that there is a JSON update that can be used to update the Split Policy. If so, could you please share the code.

The option of creating a FGDB, editing the domains and re-publishing to AGOL isn't practical if you already built a lot of maps and apps. Too many things need to be recreated after re-publishing.

It would be very helpful if esri could provide some tips and tricks specifically for REST. It could be a real time saver.

Scott_Harris

@RichSiko

Split policy might be a "read-only" property on hosted feature services (since it involves the schema). I'm not entirely sure, but that's my best guess. One suggestion would be to ask your question over on ArcGIS Online: https://community.esri.com/t5/arcgis-online/ct-p/arcgis-online Another suggestion would be to reach out to Esri Technical Support. I'm sorry I don't have a more definitive answer at this time.
