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

4
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

6
Data Model Themes

• There are many.
• Administrative
• Related Feature Use
• Rights and Interests
• Tax Parcels
• Boundaries
• Corners
• Parcel Framework
• But, wait!
• If you dont maintain it, you cant 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

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 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

14
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

15
Editing Environment

• Editing Environment
• Automatic tracked via job book
• Manual explicitly define edits

16
Basic Parcel Fabric Editing

• Parcel Traverse
• Cogo
• Line strings (natural boundaries)
• Parcel Construction
• Traversed, pasted or cogo tools
• Parcel Division
• Parcel Merge
• Remainder Parcel

17
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
