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

 Rights and Interests
 Tax Parcels
 Boundaries
 Corners
 Parcel Framework
 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 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.

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

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
 Determining where production, publication

SDE- DNR/GIO
 Multifront approach- asset management, facilities
Working with a Job

 ESRI Courses:
 Introduction to Editing Parcels Using ArcGIS Desktop
 Managing Parcel Data Using ArcGIS Desktop 10
 Using ArcGIS for Land Records Management
