More info on Parcel Data Model

by Nancy von Meyer

• 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

What is a Parcel Fabric?

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 : Fabric geometry

• Curves

- True, parametric curves

- Radial lines

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 : Line-points

• Fabric uses Line points for overlapping lines

Data Model

• Fabric allows overlapping parcels

• Natural boundaries

• Donut/island and multipart parcels

• Historic parcels

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
