About multipart, donut, and island parcels
This topic applies to ArcEditor and ArcInfo only.
You can create multipart, donut, and island parcels in the parcel fabric using part connector lines. Multipart and donut polygons can also be migrated to the parcel fabric using the Load A Topology To A Parcel Fabric geoprocessing tool or the Import Fabric Data wizard.
Multipart features are composed of more than one physical part that only references one set of attributes. Similarly, multipart parcels are composed of more than one polygon and reference one set of attributes. An example of a multipart parcel is a single parcel that is split by a right-of-way such as a road.
In the parcel fabric, you can create multipart parcels using the following methods:
- Traverse in a part connecter line between closed loops in the parcel traverse environment.
- Merge existing, disjoint parcels using the parcel merge tool. When disjoint parcels are merged, a part connection line is automatically created between the parcels.
The Load A Topology To A Parcel Fabric geoprocessing tool and the Import Fabric Data wizard will migrate disjoint, multipart polygons as multipart parcels if the polygon features are multipart features. Part connection lines are created during the data migration process.
Donut and island parcels
Donut parcels are polygons that have an interior hole. Island parcels are polygons that fill the interior hole of a donut parcel. An example of a donut parcel would be a parcel containing a lake. An example of an island parcel would be a parcel surrounded by a right-of-way parcel such as a road.
Donut and island parcels are created in the parcel fabric using part connection lines. In the traverse environment, outer parcel rings are connected to inner parcel rings using part connection lines.
The Load A Topology To A Parcel Fabric geoprocessing tool and the Import Fabric Data wizard both recognize and import donut and island parcels. You do not have to create part connection lines in the data being migrated. The part connection lines are created during the migration process. Part connection lines are created between the nearest inner ring and outer ring parcel points.
