• Set of related tables and feature classes
stored in a geodatabase
• Forms a parcel boundary network
• Explicit topology
- defined by common parcel corners, no overlaps and gaps between neighboring parcels

The Workflow A Framework for Parcel
Information Management
Data Model: Plans
• Plans
- Store and manage plans, plats, legal records…
- Parcels can be created in and grouped by their associated legal record
Data Model : Parcels Record values and Topology
• Parcel lines store (COGO) dimensions
• End points are common
- Topological integrity
Data Model : Redundancy supports Spatial Quality
• Each parcel has its own set of related lines
- Overlapping lines for a common boundary
• Redundant network
- More boundary lines define relatively fewer points
# of lines= 16
# of points = 9
Data Model : Line-points
• Line points preserve data integrity
- A line point is a parcel corner point that sits on an adjacent boundary line but does not split it
Data Model
• Fabric allows overlapping parcels
• Natural boundaries
• Donut/island and multipart parcels
• Historic parcels

Anatomy of a Parcel
• A Parcel is an Area of Land
- Related set of Lines
- Defined by From/To Points

Streamlined Workflows
• Merge parcels while maintaining interior lot lines
• Split based on new interior lines or metes & bounds descriptions
• Import digitally submitted data (from CAD files or other sources)
• Update parcel corners to more accurate data
• Number new parcels using “snake” tool
Data Integrity
• Easily and quickly incorporate new data
• Preserve parcel connectivity during incorporation
• Maintain positional relationships with other layers
(easement, right of ways, utilities, etc.)

Loading Your Data
• Multiple methods available for loading your data into a fabric
- Geodatabase feature classes and topologies
- COGO coverages
- CAD datafiles
