Public access to property information

ArcGIS for Land Records

Solve problems, support business, improve servicesSlide3

Data Management (Parcel Fabric

)

Tools within core software that support editing workflows

Splits, merges, new subdivisions & condominiums, resurveys, etc.

Optimized information model preserves record measurements

Improve integrity and positional accuracy over timeSlide4

What is a parcel fabric?

Continuous network of parcel boundariesRecord information from plans/deeds integrated into a topologically correct parcel layerSlide5

Why is the parcel fabric important to you?

Data model specifically for managing parcelsImproved workflows for managing parcelsBased on the operations you do every day – splits, combines, etc.Data integrity and accuracyHistory tracking (based on both system and legal dates)Optional metadata on plans and editorsSlide6

Data integrityLand records from plans/deeds are integrated into a continuous, topologically correct parcel layer

Reduces slivers and gapsParcel joining preserves parcel connectivity during incorporationSlide7

Data integrityFabric adjustment uses survey control and COGO dimensions to recalculate/update parcel corner points

Improving spatial accuracy over timeSlide8

Parcel history enhances integrity

Maintained automatically as you editSystem start/end and legal start/end dates supportedNot the same as geodatabase archivingSlide9

Parcel Fabric Data Model

Optimized Data Model for Parcels

Topological integrity

Improve positional accuracy of parcels and related data

History Tracking

Optionally maintain metadataSlide10

Parcel Data ModelSpecifically for managing parcels

Unit of work is the parcelConsists of a set of lines with COGO attributesLines from neighboring parcels overlap Corners are shared insuring integrity

Supports tying to control points

All organized into a connected parcel data modelSlide11

Parcels

Parcel Polygon has related lines

Lines have related pointsSlide14

Lines/Points

Lines store record dimensions

Points are stored on the ends of linesSlide15

Preserve original record dimensions, ensure topology between parcels Slide16

Overlapping Parcels

All Subdivisions, Lots, Tax Parcels, etc. are “Parcels” in the Parcel FabricSlide17

Parcel Fabric Migrations

How do you get there?Slide20

Parcel Fabric Migrations

Review the ArcGIS Help documentation(http://desktop.arcgis.com/en/arcmap/latest/manage-data/editing-parcels/loading-data-to-the-parcel-fabric.htm)Important aspects:Different paths depending on state of source dataUsing a topology to check initial data integrity

Delineating curves

Modeling parcel types (lots, subdivisions, etc.)

Annotation Slide21

Lets start migrating data

The parcel fabric expects some level of spatial integrity to startQuestion #1 – How well do your tax parcels, boundaries, lots, etc. line up? Parcel Fabric MigrationsSlide22

Question #2 – How are curves represented within your data?

Parcel Fabric MigrationsSlide23

Ultimately, you’ll follow a process similar to this:

Step 1 - Prepare your Fabric Data ModelStep 2 - Prepare your Source DataStep 3 - Clean up the Geometry on your Source Data

Step 4 - Establish Topology Required for Fabric Loading

Step 5 - Load your Source Data to the Fabric

Step 6 - Set up your Editing Map

Parcel Fabric MigrationsSlide24

Exercise 1

Migrate your data to a parcel fabricSlide25

Exercise 1

Because a Topology cleanup is required you’ll need to ensure your data is in a geodatabase. Step 1 – Create a new empty geodatabase (If your data is already in a geodatabase move to Step 2)Step 2 – Create a new Feature DatasetStep 3 – Move your data into the new Feature DatasetStep 4 – Create a new Topology, add Polygon Feature ClassStep 5 – Add a rule to the polygons for No OverlapStep 6 – Validate the Topology

Step 7 – Start an Edit Session in ArcMap

Step 8 – Fix all of the overlapping errors and

ReValidate

Step 9 – Save your edits and Stop EditingSlide26

Exercise 1

Step 10 – Delete the Topology LayerStep 11 - Create a Point Feature Class from your polygonsStep 12 – Create a Line Feature Class from your polygonsStep 13 – Delete the Polygon Feature ClassStep 14 – Add the Lines to ArcMap and Start EditingStep 15 – Planarize your Line Feature Class

Step 16 – Use the Curves and Lines tool to locate bad curves

Step 17 – Fix all of the bad curves

Step 18 – Save your edits and Stop EditingSlide27

Exercise 1

Step 19 – Create a new Poly FC from the Lines FC, & use the PointsStep 20 – Create a new Topology LayerStep 21 – Add the Polygon and Line Feature ClassesStep 22 – Use the .RUL file to load the 6 Topology RulesStep 23 – Validate the topologyStep 24 – Add the Topology to ArcMap, & add all layers when askedStep 25 – Start Editing

Step 26 – Fix all of the topology errors

Step 27 –

ReValidate

the Topology

Step 28 – Save your edits and Stop EditingSlide28

Exercise 1

Step 29 – Add two fields to the source polygon feature class- Name (Text)- Type (Long Integer)Step 30 – Start editingStep 31 – Calculate the Type field to “7”Step 32 – Calculate the Name field to equal your Pin fieldStep 33 – Save your edits and Stop Editing

Step 34 – Right click inside the Feature Dataset and create a new Parcel FabricStep 35 – Add any fields to the Fabric Polygon class that you need to come over from the source polygon feature classSlide29

Exercise 1

Step 36 – Locate the “Load A Topology To A Parcel Fabric” geoprocessing tool and run itStep 37 – Point to your new Parcel Fabric and source polygon feature classStep 38 – Enter 300 for the natural boundaries settingStep 39 – Use acres, feet, and DMSStep 40 – Click RunStep 41 – After complete, right click on Parcel Fabric and change the schema to the Local Government Information ModelStep 42 - Drag and drop the Parcel Fabric into ArcMap
