Append data to the parcel fabric

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, the feature dataset should be registered as unversioned. Versioning adds a number of system maintained tables, indexes, and attributes that can increase the processing time of data loading operations.

Data loading should be done before enabling the parcel topology. If topology is enabled when appending data, dirty areas will be created for each new feature loaded, and this will add processing time to data loading operations and other topology-related operations. To append data after a topology is enabled, disable the topology, append the data, and reenable the parcel topology.

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.

If your source parcels have subtypes, use the Add Subtype geoprocessing tool to add subtypes to your parcel types. The subtype codes in your source parcels should match the new subtype codes created for your parcel types.

Parcels are loaded into the parcel fabric by appending parcel features into the parcel type feature classes. Parcel data can be appended to either the parcel type polygon or the parcel type line feature class. Polygons should be appended 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.

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:

  1. 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.
  2. Click the Analysis tab and click Tools to open the Geoprocessing pane.
  3. Search for and open the Append tool.
  4. 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.

  5. 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 have 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.

  6. Click Run to execute the tool and append your polygons.
  7. Create and assign records to your parcel type polygons, build parcels, and enable the parcel topology.

    Building parcels will create missing lines and points.

Append parcel lines

The parcel type lines feature class is a COGO-enabled lines feature class that stores parcel boundary lines and COGO dimensions. Polygons should be appended 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.

  1. 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.
  2. 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.
  3. 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.

  4. 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.

  5. Click the Analysis tab and click Tools to open the Geoprocessing pane.
  6. Search for and open the Append tool.
  7. Choose your input polygon feature class.
  8. 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 lines feature class. Attribute fields should map to both the system attribute fields and any other attribute fields that you have 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.

  9. Click Run to execute the tool and append the polygons.
  10. Create and assign records to your parcel type polygons, build parcels, and enable the parcel topology.

    Building parcels will create missing lines and points.

  11. Use the Transfer Attributes geoprocessing tool to transfer attributes from your source lines to the built lines in the parcel fabric.

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 (fixed or unfixed).

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 right of ways and to connect parcel corners to control points.

Learn more about connection lines

  1. 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.
  2. Click the Analysis tab and click Tools to open the Geoprocessing pane.
  3. Search for and open the Append tool.
  4. Choose your input connection lines feature class.

    You may need to add a definition query to query for your connection lines.

  5. Choose the parcel fabric Connection Lines feature class as the target dataset.
  6. 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 feature class.

  7. Click Run to execute the tool and append your data.

Load parcel records

Use the Create Parcel Records geoprocessing tool to load and assign parcel records to parcel features using a record name field.

The tool creates records based on record names that are added to an attribute field on the input parcel feature class. New records are added to the Records feature class, and record polygons are created based on the cumulative geometry of all parcel features having a matching record name. The Created By Record attribute field of the parcel features is updated with the global ID of the new records.

Use the Create Parcel Records tool to create records for parcel type polygons before building parcels. When parcels are built, the record information will be transferred to the parcel lines and parcel points.

Use the Append geoprocessing tool to append record information in your source data to the parcel fabric Records feature class
