The Who and What SLO Does
Oldest Indiana office, established in 1878IDOA division embedded within IDNR
Intent to work closely with DNR AcquisitionMaintains 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 approvalCorrecting tax parcel informationBoundary verificationQA/QC deedsAssisting asset managementHealthy Rivers InitiativeCalculating official acreage (owned/managed)Parcel centralized model for state governmentParcel 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

But, wait! If you don’t maintain it,
you can’t include it!

Parcel Fabric Excellence in 6 easy steps
1. Prepare your fabric data model2. Prepare the source data – not your
production db3. Clean up geometry on source data4. Establish the topology5. Load source data to the fabric6. 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 polygons convert to lines•GP is performance intensive•Limited to under 5K lines•Tools to assist Topo GP
•Multipart to Singlepart•Planarize Lines•Split Line at vertices
Topology Rules Line Feature class:
Must be covered by boundary of polygon feature
Must no self overlap Must be single part Must not intersect or
touch interior Polygon Feature class:
Must be covered by boundary of line feature
Migrate: Import Fabric Data Wizard
Used to migrate whole datasetsDoes 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 DivisionParcel MergeRemainder 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

Where are we in the process
Still working through process of migration Nuances in the details Several trial runs Half processed
Abridged workflow to QA old, as well as move through new
