10 What is a Parcel Fabric? 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

17 Scope of Technology The Workflow A Framework for Parcel Information Management Land Records Submitted to Agency Geodatabase Agency Creates Digital Parcels Integrate parcels with the existing Fabric Parcel Fabric

18 Data Model : Relationships Plans 1 1-M Parcels

19 Data Model: Plans Plans - Store and manage plans, plats, legal records - Parcels can be created in and grouped by their associated legal record

20 Data Model : Relationships Plans 1 1-M Parcels 1 1-M Points M Lines

21 Data Model : Parcels Record values and Topology Parcel lines store (COGO) dimensions End points are common - Topological integrity

22 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

23 Data Model : Fabric geometry Curves - True, parametric curves - Radial lines

24 Data Model : Relationships Plans 1 1-M Parcels M Points M Lines Line Points 0-M

25 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

26 Data Model : Line-points Fabric uses Line points for overlapping lines

27 Data Model Fabric allows overlapping parcels Natural boundaries Donut/island and multipart parcels Historic parcels

28 Data Model : Relationships Plans 1 1-M Parcels M 1 Points M Lines 0-1 Control Line Points 0-M

29 Anatomy of a Parcel A Parcel is an Area of Land

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

31 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

32 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.)

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

35 Loading data into the Parcel Fabric Data Model Lots Lot_Polygons Lot_Lines Lots_Topo Parcels Parcels Parcel_Lines Parcels_Topo Parcel Model Line Must be Single Part Line Must Not Self-Overlap Line Must Not Self-Intersect Line Must Not Intersect Or Touch Interior Line Must be Covered by Boundary Of (polygon) Polygon Boundary Must be Covered By (Line) Geodatabase
