Add support for Shape_Length and Shape_Area labelling when publishing to AGOL and Enterprise

David_Brooks

Currently, you can label features in ArcGIS Online based on the Shape_Length and Shape_Area fields.

You can also do this in ArcGIS Pro.

However, you cannot publish a feature service with these labels, instead you get these errors.

So both environments support it, but the sharing process doesn't. 

Simple fix?

Disregard.

I don't have much experience with AGOL or Enterprise, but this might be a viable workaround for Enterprise:

For Enterprise, you might be able to create a database view or a query layer that has a calculated field for LENGTH.

For example, in Oracle, it would be:

SELECT 
   SDE.ST_LENGTH(SHAPE) AS SHAPE
   --other fields
FROM
    MY_FC

The same would apply for AREA: SDE.ST_AREA(SHAPE).

I imagine you could publish the query to Enterprise and label based on that calculated field.

Notes:

• If using a database view, you might need to register the view with the geodatabase.
• The problem with using a view or a query layer might be: neither is editable.
• If you want to edit the layer in Enterprise, then maybe an attribute rule could be used instead to populate a LENGTH field in the actual feature class.

Just thinking out loud as a non-expert. I agree that out-of-the-box functionality would be better. 

 

Edit:

After re-reading your question, I see that you specifically want to publish a feature service, likely for editing. So the idea above for creating a query won't work. Please disregard.

Can you create dynamic joins in Enterprise? For example, could you create a view or query layer that has a calculated LENGTH field, then create a dynamic join from the FC to the query, allowing you to still edit the FC in the feature service, but also letting you label using the joined query's LENGTH field?
