Parcel data is loaded into the parcel fabric by appending source data to parcel fabric feature classes.
If you have an ArcMap parcel fabric, upgrade the parcel fabric instead of loading data into a new parcel fabric.
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.
Add parcel types
Parcels are stored in 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 a parcel fabric. The tool creates a polygon and line feature class and adds the feature classes to the geodatabase topology. You can add as many parcel types as necessary for your organization.
Parcels are added to the parcel fabric by appending parcel features to the parcel type feature classes. Parcel features can be appended to both the parcel type polygon and the parcel type line feature class.
If the source parcel data includes parcel lines with missing or unreliable dimensions, polygons should be appended. Lines are created when parcels are built and are topologically aligned with the parcel polygon. Topology errors such as gaps and slivers are minimized.
You do not need to append data to both the parcel type polygon and line feature classes. Missing parcel features are created when parcels are built.
To append parcel polygons to a parcel type follow these steps:
- Confirm that you added your organization's necessary attribute fields, domains, and subtypes to the parcel type feature classes. Also ensure that the source parcel data maps to the system-added parcel fabric domains.
- Open the Append geoprocessing tool and choose the input polygon feature class.
You may need to add a definition query to the source parcel polygon feature layer to query for the parcel type.
- Choose Use the Field Map to reconcile schema differences for Schema Type.
You will map the attribute fields in the 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 the source feature class for them to map to the parcel type feature class.
- Click Run to run the tool and append the polygons.
- Follow these steps to create records and build parcels.
Append polygons and lines
You can use the Append tool to append both polygons and lines to the parcel fabric.
When appending lines with COGO attributes, 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 the parcel fabric.
After appending lines and polygons, Follow these steps to 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 are 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.
To append lines as connection lines, complete the following steps:
- Confirm that you added any necessary attribute fields and domains to the connection lines feature class. Also ensure that the 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 the input connection lines feature class.
You may need to add a definition query to query for the connection lines.
- Choose the parcel fabric Connection Lines feature class as the target dataset.
- Choose Use the Field Map to reconcile schema differences for Schema Type. You will map the attribute fields in the 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 the existing lines feature class for them to map to the parcel fabric Connections Lines feature class.
- Click Run to run the tool and append the data.
