ArcGIS Pro 2.5: How does the fabric feature classes and their ID fields work in case of parcel merging and dividing?

 

I couldn’t figure out how fabric feature classes (parcels, records, and historic parcels) and their ID fields (global ID, created by record, retired by record) are generated in case of parcel merging and dividing.

To get a better understanding of the 'parcel aware' editing tools make sure you first understand the behavior that is described in the meetup:  Video Link : 6073 

The GlobalIDs are the primary key (PK) of any feature: parcel, line, point, connection line, and records.

They are determined by the system and are unique across systems (unlike object IDs).

When they are used as a Foreign key (FK)  - for example in the CreateByRecord field, they should match the Record that was the active record during the creation of the feature, regardless if a relationship class is in place or not.

When merging a new parcel '555' from parcels '222' and '333' with an active record 'AAA' - you will see that the GlobalIS of record 'AAA' will be written to the 'RetiredByRecord' field of parcels '222' and '333' as well as to the ;CreatedByRecord' field of the new child parcel '555'.

I hope this answers your question

Thank you Amir for the elaboration.

 

Now, it’s much clearer. However, I couldn’t figure out why this structure is not able to return the history as parcels are kept divided

 

For example, in the screenshot below, parcel#3 is divided into 3/1 & 3/2. Then parcel#3/1 is divided into 3/1/1 & 3/1/2. Identifying 3/1/1 doesn’t return all its history which is parcel#3/1 and parcel#3

Hi Jamal,

I assume you use the editing Divide tool with an active record.

If you do it SHOULD create historic parcels and populate the RetiredByRecord with the Global ID of the Active Record. If you are using an old version of ArcGIS Pro (2.4) - you might not get this 'parcel behavior'.

Thanks Amir

 

Let me re-describe the scenario as follows:

 

- In the 1st screenshot, I got identical parcel layer and record layer.

- Now, Parcel#38 is split into two parcels: 38/1 and 38/2.

- Then how these two created parcels are recorded in the record layer so that parcel#38/1 can be newly split into 38/1/1 and 38/1/2?

I got that all can be managed if we just consider two layers: parcel and records. No need for the default symbology. After each parcel edit, you need to apply “create parcel records”

and “build extent” tools

 

 

In the screenshot below:

 

Parcel#23 is set as an active record

Parcel#23 is split into 23/1 & 23/2

The “create parcel records” tool is performed

The “build extent” is run

 

Parcel#23/1 is set as an active record

Parcel#23/1 is split into 23/1/1 & 23/1/2

The “create parcel records” tool is performed

The “build extent” is run

 

And so on!

 

This way, the identify tool brings the history correctly if we work only with these two layers (parcel and records)
