The Who and What SLO Does
Oldest Indiana office, established in 1878
IDOA division embedded within IDNR
Intent to work closely with DNR Acquisition
Maintains record maps for all state agencies
Excludes INDOT/colleges and universities
Past and present - EAS, DED, CONEAS, WRD
Authority within Indiana on state owned property
Including legal descriptions, surveys, etc.
Over 6,500 deeds

Current Projects
Acquisition - legal approval
Correcting tax parcel information
Boundary verification
QA/QC deeds
Assisting asset management
Healthy Rivers Initiative
Calculating official acreage (owned/managed)
Parcel centralized model for state government
Parcel fabric – production vs publication parcels
Beginning SLO version x.1??
Preserving survey and measurement data
Cogo, line strings (i.e. relative calls)
Integrating attachments
Surveys, supporting documents, etc
Broaden the scale
Not the data model, but part of something larger
Managing restrictions
For acreage calculations
Understanding interests and rights vs acquisition
Other outstanding issues
Opportunitas tandem: Parcel Fabric Solution
The Parcel Fabric
Dataset for storage,
maintenance and editing of
parcels
Historical parcels
Linework adjustment
Coincident geometry
Topology shared across
Production vs publication
Tax Parcels/ CAMA
Public access to data

Parcel Fabric Excellence in 6 easy steps
1. Prepare your fabric data model
2. Prepare the source data – not your production db
3. Clean up geometry on source data
4. Establish the topology
5. Load source data to the fabric
6. Set up your editing map
Don’t go in the woods…..Alone!

Loading Data into a Parcel Fabric
ESRI White Paper – April 2011
Okay, but where do I start?
Option A: Create a PF from scratch
Good in theory, but not really practical for large data sets.
Option B: Migrate Existing dataset
Load A Topology To a Parcel Fabric Geoprocessing tool
Geometry-based topology with a set of required rules is validated
against a subset of selected data or an entire dataset
Import Fabric Data wizard
Imports a formatted dataset of points, lines, and polygons
Same as a COGO coverage.
**No longer needs to be formatted into fabric source dataset to be
migrated into a parcel fabric as was prior to ArcGIS 10.
Words to live by….

Migrate: Load A Topology to a PF GP Tool
•Requires valid topology
•If dataset contains only
Topology Rules
polygons convert to lines
•GP is performance intensive
•Limited to under 5K lines
•Tools to assist Topo GP
Must be covered by
boundary of polygon feature
Must no self overlap
Must be single part
Must not intersect or touch
interior
•Multipart to Singlepart
•Planarize Lines
•Split Line at vertices
Line Feature class:
Polygon Feature class:
Must be covered by
boundary of line feature
Migrate: Import Fabric Data Wizard
Used to migrate whole datasets
Does need to be formatted into parcel source
Parcel lines
Parcel corner points (nodes)
Parcel polygons
Use PF Source Builder Toolbar
ArcScripts
Data migration process builds fabric parcels using
dimensions stored in COGO of source parcel
Some topology also required
Editing Environment
Editing Environment
Automatic – tracked via job book
Manual – explicitly define edits
Basic Parcel Fabric Editing
Parcel Traverse
Cogo
Line strings (natural boundaries)
Parcel Construction
Traversed, pasted or cogo tools
Parcel Division
Parcel Merge
Remainder Parcel
Least Squares Adjustment
1st run check on control points
All are included in best fit
stored bearings
distances on parcel lines
control points
Repeated until maximum
displacement in northings and
eastings close to zero
Original COGO not altered
