ArcGIS Parcel Fabric

 A city’s parcels dataset is used to maintain ownership and tax information, record zoning and other planning designations, track annexations, maintain corporate boundaries, and develop future land-use plans.

ArcGIS Parcel Fabric – Records Feature Class:

What is a “Records” feature class? It’s derived from from legal descriptions filed in county recorder offices and includes detailed measurements for property dimensions and public rights of way.

Geometry and Connectivity

• Geometry: Features in the Records feature class correspond to the extent of parcels associated with each record. How is this possible?
• Connectivity with Other Feature Classes:
  • Relationship Classes: One-to-many relationships between Parcel Type objects (e.g., lot polygons) and the Records feature class using GlobalID keys and Created By Record fields.
  • Must Have a Record Attribute Rule: A validation rule ensuring every parcel (both polygon and line) is associated with a record.

Creating and Assigning Parcels to a Record

• Step-by-step process:
  1. Select a parcel lot.
  2. Go to the Records tab and create a new record (e.g., LandTransaction1).
  3. Set a Recorded Date and create the record.
  4. Assign the selected parcel to the new record.
• Result: The record feature now has associated geometry and labels, including the parcel polygon and lines.

Minimum Topology rules required by the parcel loader to load data to the fabric

1. { LINES } Must Not Self-Overlap
2. { LINES } Must Not Self-Intersect
3. { LINES } Must Not Intersect or Touch Interior
4. { LINES } Must Be Covered by Boundary Of
5. { POLYGONS } Boundary Must be Covered By
6. { LINES } Must be Single Part
