Parcel data is loaded into the parcel fabric by appending source data to parcel fabric feature classes. Parcels are loaded into the parcel fabric as parcel types, such as ownership parcels or administration parcels.
Note:
If you have an ArcMap parcel fabric, upgrade the parcel fabric instead of loading data into a new parcel fabric.
Note:
When loading data, especially large datasets, register the feature dataset as unversioned. Versioning adds a number of system maintained tables, indexes, and attributes that can increase the processing time of data loading operations.
Load parcel types
Parcels are added to the parcel fabric as parcel types. Examples of parcel types are ownership parcels, administrative parcels, and subdivision parcels. A parcel type is defined by a separate polygon and line feature class, and both parcel polygons and lines are associated with the parcel record.
Use the Add Parcel Type geoprocessing tool to add a parcel type to your parcel fabric. The tool creates a polygon and line feature class and adds the feature classes to the parcel fabric topology. You can add as many parcel types as necessary for your organization.
Parcels are loaded into the parcel fabric by appending parcel features into the parcel type feature classes. Parcel data can be appended to the parcel type polygon and the parcel type line feature class. When polygons are appended, records can be associated correctly with parcels. If you are appending reliable parcel lines with COGO dimensions, convert the lines to polygons, append the polygons to the parcel fabric, build parcels, and transfer the source line attributes to the built parcel lines. In this way, records can be correctly associated with the parcel lines.
If your source parcel data has parcel lines with missing or unreliable dimensions, polygons should be appended. Lines will be created when parcels are built. Lines will be topologically aligned with the parcel polygon, and parcel topology errors such as gaps and slivers will be minimized.
You do not need to append data to both the parcel type polygon and line feature classes. Missing parcel features will be created when parcels are built.
Append polygons
To append parcel polygons to the parcel fabric, follow these steps:
- Before appending data, confirm that you added your organization's necessary attribute fields, domains, and subtypes to the parcel type feature classes. Also ensure that your source parcel data maps to the system-added parcel fabric domains.
- Open the Append geoprocessing tool and choose your input polygon feature class.
You may need to add a definition query to your source parcel polygon feature layer to query for your parcel type.
- Choose Use the Field Map to reconcile schema differences as the Schema Type.
You will map the attribute fields in your source polygon feature class to the attribute fields in the parcel type polygon feature class. Attribute fields should map to both the system attribute fields and any other attribute fields that you added to the parcel type feature class. You may need to recalculate or re-create the attribute fields in your source feature class for them to map to the parcel type feature class.
- Click Run to execute the tool and append your polygons.
- Follow these steps to create records and build parcels
Append parcel lines
The parcel type lines feature class is a COGO-enabled lines feature class that stores parcel boundary lines and COGO dimensions. When appending lines only to the parcel fabric, the lines should be converted to polygons so that records can be associated correctly with parcels. If your source data has reliable parcel lines with COGO dimensions, convert the lines to polygons, append the polygons to the parcel fabric, build parcels, and transfer the source line attributes to the built parcel lines.

- Before appending data, confirm that you added your organization's necessary attribute fields, domains, and subtypes to the parcel type feature classes (polygon and line). Also ensure that your source parcel data maps to the system-added parcel fabric domains.
- If your source lines have densified curves (curves comprised of tiny line segments), use the Simplify By Straight Lines And Circular Arcs geoprocessing tool to convert densified arc curves to true curves.
- For each parcel type, use the Feature To Polygon geoprocessing tool to generate polygons from the source lines.
Polygons should be in separate feature classes for each parcel type.
- Populate any necessary attribute fields, domains, and subtypes on the polygon feature class that you want to transfer to the parcel type polygon feature class.
You will transfer attributes from the source line feature class to the built lines in the parcel fabric later in the workflow.
- Open the Append geoprocessing tool and choose your input polygon feature class.
You may need to add a definition query to your source parcel polygon feature layer to query for your parcel type.
- Choose your input polygon feature class.
- Choose Use the Field Map to reconcile schema differences as the Schema Type.
You will map the attribute fields in your source polygon feature class to the attribute fields in the parcel type polygon feature class. Attribute fields should map to both the system attribute fields and any other attribute fields that you added to the parcel type feature class. You may need to recalculate or re-create the attribute fields in your existing feature class for them to map to the parcel type feature class.

- Follow these steps to create records and build parcels
- Use the Transfer Attributes geoprocessing tool to transfer attributes from your source lines to the built lines in the parcel fabric.
Tip:
Use the Migrate COGO to ArcGIS Pro script tool to convert COGO text values to the numerical standard used for COGO-enabled line features in ArcGIS Pro.
Append both polygons and lines
You can append both polygons and lines to the parcel fabric. Since lines can be shared between parcels, the line may be used by adjacent parcels that have different records. When building the parcel fabric after appending polygons and lines, lines will be associated with the record from the adjacent parcel that has the most recent legal date. If the records associated with adjacent parcels have the same legal date, or no legal date, a record is randomly chosen from one of the shared parcels and associated with the line.
Use the Append geoprocessing tool to append lines and polygons to your parcel type. Create records and build parcels.
Append points and control points
When you first get started with the parcel fabric, you are not required to load parcel points. When building parcels, missing points will be created.
Use the Import Parcel Fabric Points geoprocessing tool to update existing parcel fabric points or import new points.
Append lines as connection lines
The Connection Lines feature class is a COGO-enabled lines feature class that stores parcel fabric connection lines. Connection lines are necessary to connect parcel corners across rights-of-ways and to connect parcel corners to control points.
- Before appending data, confirm that you added any necessary attribute fields and domains to your connection lines feature class. Also ensure that your source parcel data maps to the system-added parcel fabric domains.
- Click the Analysis tab and click Tools to open the Geoprocessing pane.
- Search for and open the Append tool.
- Choose your input connection lines feature class.
You may need to add a definition query to query for your connection lines.
- Choose the parcel fabric Connection Lines feature class as the target dataset.
- Choose Use the Field Map to reconcile schema differences as the Schema Type. You will map the attribute fields in your existing lines feature class to the attribute fields in the parcel fabric Connections Lines feature class. Attribute fields should map to both the system attribute fields and to any additional attribute fields. You may need to recalculate or re-create the attribute fields in your existing lines feature class for them to map to the parcel fabric Connections Lines feature class.
