  1. Migrating Data To The Parcel Fabric Christine Leslie Amir Bar-Maor

  2. What is a parcel fabric? • Dataset of related feature classes and tables • Polygons, lines, points, plans, etc. • System attributes • Connected parcel groups • Forms a parcel boundary network • Explicit topology • Defined by common parcel corner points • Parcel Editor toolbar Migrating Data To the Parcel Fabric

  3. Parcel fabric data model Plans Parcels 1 1-M Lines Points 1 1-M 2-1 1 0-1 0-1 Line Points Control 0-M Migrating Data To the Parcel Fabric

  4. Parcel fabric data model Line points • Preserve original recorded dimensions, ensure topology between parcels Migrating Data To the Parcel Fabric

  5. Parcel fabric data model Overlapping parcels Subdivisions, Lots, Tax Parcels, Historic parcels all share same common points Migrating Data To the Parcel Fabric

  6. Parcel fabric data model • Data model can be optimized for your organization, for example, esri’sLocal Government Information Model Migrating Data To the Parcel Fabric

  7. Local government Information Model (LGIM) • GIS datasets, web services, maps and apps • GIS information and processes are organized across departments • Parcel fabric is used for parcel editing • Parcel fabric can be enabled with the LGIM Migrating Data To the Parcel Fabric

  8. Parcel fabric enabled with the LGIM • Extends the parcel fabric data model • Optimized for parcel editing in the USA • Provides a configured map for streamlined editing • Provides automated parcel editing workflows Migrating Data To the Parcel Fabric

  9. Demo Amir Bar-Maor Migrating Data To the Parcel Fabric

  10. Migrating data to the Parcel Fabric • Setup the data model • Extend the parcel fabric model • Or use the Local Government Information Model • Setup a staging environment • Format and prepare data • Use the Load a Topology to a Parcel Fabric geoprocessing tool • Import control points Migrating Data To the Parcel Fabric

  11. Migrating data to the parcel fabric Steps 1. Create a parcel fabric 2. Setup staging & create attributes 3. Prepare geometries 4. Load data 5. Configure the map 6. Import control points Migrating Data To the Parcel Fabric

  12. Step 1: Create a parcel fabric Data migration steps • Create in a feature dataset • Projected or geographic • Extend the data model • Add you own attributes, tables • Or enable the Local Government Information Model (USA) Migrating Data To the Parcel Fabric

  13. Demo: Step 1 Amir Bar-Maor Migrating Data To the Parcel Fabric

  14. Step 2: Setup staging & create attributes Data migration steps • Review source data • Inventory of polygons • Create an empty polygon feature class for each parcel type • In a separate feature dataset • Add and map attribute fields • Fields must match fields in parcel fabric tables (both system and additional) • Calculate any necessary attributes in source polygons • Types, historic parcels • Use Simple Data Loader • Load your source polygons into new empty polygons Migrating Data To the Parcel Fabric

  15. Step 2 cont…Staging Data migration steps • Use the LGIM • Staging feature classes are setup for you • Download and unpack the staging layer package • Other considerations • Check alignment between parcel types Migrating Data To the Parcel Fabric

  16. Demo: Step 2 Amir Bar-Maor Migrating Data To the Parcel Fabric

  17. Step 3: Prepare geometries Data migration steps • For each parcel type: • Check and repair any polygon geometries • Polygons to lines • Curves and lines Add-in • Rebuild polygons • Check polygon inventories Migrating Data To the Parcel Fabric

  18. Demo: Step 3 Amir Bar-Maor Migrating Data To the Parcel Fabric

  19. Data migration steps 1. Create a parcel fabric 2. Setup staging & create attributes 3. Prepare geometries 4. Load data 5. Configure the map 6. Import control points Migrating Data To the Parcel Fabric

  20. Step 4: Load data Data migration steps • Load a Topology to a Parcel Fabric geoprocessing Tool • Separate topologies for each parcel type • Topology validated against a required set of rules Migrating Data To the Parcel Fabric

  21. Demo: Step 4 Amir Bar-Maor Migrating Data To the Parcel Fabric

  22. Steps 1 to 4: Summary of staging • Polygon feature class for each type • Separate feature datasets • Add/map fields for migration to fabric • Create lines • Format lines • Rebuild polygons from lines • Create/validate topologies • Load topologies • Load source polygons using Simple Data Loader Migrating Data To the Parcel Fabric

  23. Step 5: Configure your map Data migration steps • If using the LGIM: • Drag LGIM-enabled parcel fabric into the map • If using your own model • Query parcels and save layer files Parcel fabric layer enabled with the LGIM Migrating Data To the Parcel Fabric

  24. Demo: Step 5 Amir Bar-Maor Migrating Data To the Parcel Fabric

  25. Step 6: Import control points Data migration steps • Why have control? • Accuracy for new parcels • Deeds references control points • Use Import Control Points wizard • Use XYZ coordinates or shape geometry • Loaded multiple times for new updates to coordinates Migrating Data To the Parcel Fabric

  26. Demo: Step 6 Amir Bar-Maor Migrating Data To the Parcel Fabric

  27. Additional considerations • Script to automate the loading process • Takes polygons, creates lines, validates topology and loads data • Polygons must be typed • On Github • Iterate tool for large datasets • Divide into zones • Overlapping parcels of the same type • Planarize your lines • Starting with lines instead of polygons • Format lines, type lines, build polygons Migrating Data To the Parcel Fabric

  28. Resources • Documentation • Latest release of help documentation • videos • Land Records resource center • Local Government Information Model • Data migration staging package • Add ins (Iterator, Curves and Lines, etc.) • Land Records meetup Migrating Data To the Parcel Fabric

  29. Additional sessions • Editing and Maintaining Parcels • Tuesday, July 15th, 1:30pm – 2:45pm, 14B • Thursday July 17th, 10:15 – 11:30am, 14B • Parcel Editing: Advanced • Wednesday, July 16th, 10:15am – 11:30am, 06B • Thursday, July 17th, 1:30pm – 2:45pm, 06D • Land Records Meetup • Thursday, July17th, 12pm – 1pm, 31B Migrating Data To the Parcel Fabric
