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

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

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
