5 Goals Discuss real-world examples of how Municipalities are currently using, maintaining, and sharing Parcel Mapping Understand the needs and drivers of Parcel Mapping for municipalities Demonstrate the capabilities of the Esri solution for Parcel Mapping

6 Status of Municipal Parcel Mapping

7 Need for Municipal Parcel Mapping There is an increasing, multi-sector need for Parcel Mapping Insurance Risk Assessment Emergency Management Real Estate Viewing Utility Asset Management

8 Needs of Parcel Mapping Users Consistent and complete coverage across jurisdiction (local, regional, provincial, interprovincial) Currency updates (changes only) as they occur Content that reflects their business needs Appropriate (not maximum) spatial accuracy Referential Integrity Easy, simple and flexible accessibility and usage (licensing and technical) Minimal/predictable movement due to spatial adjustments Simple, realistic and cost-effective licensing Integrated life cycle approach

9 Needs of Parcel Mapping Maintainers (business drivers for modernization) Move from custom to COTS-based solutions Replace unsupported legacy systems Leverage modern technology and service oriented architectures Achieve parcel mapping accuracy, consistency, and currency that is compatible with general business needs Adopt modern approaches to simplify workflow and reduce parcel mapping maintenance costs and timelines Collaborate with other stakeholder organizations to reduce/share costs and add value

10 Trends and Innovations in Parcel Mapping

13 Case Studies

14 Case Study: Township of Langley Digital Submission of Plans Digital plan submission standards; Increases parcel mapping efficiency: - Reduces duplication of effort; - Reduces mapping errors; - Faster mapping updates; - Easier to share plans. Standardized CAD layering specification is employed. Private developers, contractors and our own Operations crews rely on accurate electronic mapping information. The use of electronic files provides the ability to increase the accuracy, integrity and reliability of the Township s GIS data. Township of Langley Digital Submissions Q&A

15 Case Study: Oxford County Condo Town

16 Case Study: City of Calgary Accuracy Heat Map

17 Group Discussion

18 Group Discussion Does your municipality maintain its own parcel mapping, or do you rely on parcel mapping services? How important is it to capture parcels during the development process? How important is spatial accuracy and currency to your parcel mapping? What are other challenges and/or opportunities with your municipal parcel mapping activities? Other?

19 Understanding the Parcel Fabric

20 Parcel Editing in ArcGIS ArcGIS Pro ArcGIS for Desktop

21 What is a Parcel Fabric? Set of related tables and feature classes stored in a geodatabase Forms a parcel boundary network Explicit topology - defined by common parcel corners, no overlaps and gaps between neighboring parcels

22 Parcel Fabric Key Points An information Model more than just shapes! Manages topological relationships Complex object in a geodatabase Set of related tables and feature classes stored in a geodatabase Forms a parcel boundary network Higher level of data integrity

23 Why use the Parcel Fabric? Optimized data model for maintaining Parcels Preserves original recorded information Ensures topology between Parcels Supports overlapping Parcels Maintains Historic Parcels Efficient workflows Adjust to Control Create a more accurate Parcel Layer

24 Components of the Parcel Fabric Data Model

25 What s in a Parcel Fabric? Lines Points Parcels Linepoints Plans Parcel Fabric Control Points

26 Parcel Fabric Data Model Relationships

27 How Parcel Fabric Data is Stored

28 Plans Store and manage plans/legal records Parcels can be created in and grouped by their associated legal record

29 How Parcel Fabric Data is Stored

30 How Parcel Fabric Data is Stored

31 How Parcel Fabric Data is Stored

32 How Parcel Fabric Data is Stored

33 Parcel Attributes Attribute data correct dimensions - COGO Data entry and storage - Parcel Misclose information - Area based upon dimensions

34 Demo Exploring parcel fabric elements and relationships in the data model

35 High Level Parcel Editor Workflows and Concepts

36 Data Integrity of Parcels in a Fabric Topological accuracy - Parcels are joined using shared points

37 Redundancy supports Spatial Quality Each parcel has its own set of related lines - Overlapping lines for a common boundary Redundant network - More boundary lines define relatively fewer points - Reduces chance of using incorrect measurements

38 Line Points Added to existing parcel point when: - Point is on boundary of adjacent parcel Does not split the boundary line

39 Line Points (cont d) Preserve original record dimensions Ensure topology between parcels

40 Parcel Structures Parcel Fabric supports the following: - Overlapping Parcels - Natural Boundaries (line strings) - Donut/island and multipart parcels - Historic parcels - Unclosed Parcels - Joined and Unjoined Parcels

41 Conventional Update Process Paper survey plan COGO and CAD editing Issues - Incomplete information - Time consuming and error prone - Large shift requires warping or remapping - New (better) plan often warped to (worse) fabric - Source information discarded after input

42 Esri Parcel Mapping Approach Capture Join Adjust

43 Parcel Fabric Update Process Capture - Capture the survey information (COGO) - All plan information is captured and retained (parcel descriptions, plan bearings and distances, control, confidence, source) - Can use digital plan submission (CAD) Join - Connect common points into the fabric - No need to make final decisions on the placement of the parcel Adjust - Fabric can be readjusted from source (Lease Squares Adjustment) - Computed confidence level

44 Large Scale Readjustment Collect real world positions of corners - Survey grade GPS (PPP / RTN) - Photo-recognizable control - From high resolution aerial imagery Use metadata to readjust area - Control, measurements, relative weights, interconnectivity Accept or reject new adjustment

45 Demo Review of the Capture> Join> Adjust Methodology

46 Common Parcel Editor Tools

47 Modify/Update Parcel Editor Tools Parcel Maintenance Tools Includes tools like: Parcel Division, Parcel Remainder, Parcel Merge Parent parcels become historic automatically Historic parcels are not deleted (user manages deletion of parcels) Construction Tools (Construct from Parent) Includes tools like: Breakline Tool, Create Parallel Offset Allows you to build new parcels based on existing parcel lines

48 Demo Using Common Parcel Editor Tools to Maintain the Parcel Fabric

49 Esri Canada Approach to Implementing Parcel Editing in ArcGIS

50 Esri Canada Approach Readiness Review A review of your current parcel mapping data Quantify the effort to make your data Parcel Fabric ready Understanding the benefits of the Parcel Fabric Model Data Migration Workshop(s) Fabric Maintenance Workshop(s) Implementation Support Data migration is about half the effort of a Parcel Mapping project Discussion of best practices for a successful data migration Map current parcel data into the parcel fabric model A review of the various out of the box parcel editor tools An understanding of how these tools can be used to complete end to end parcel mapping workflows Ongoing operations support as your staff learns to work with the Esri Parcel Mapping Solution

51 Canadian Parcel Data Model Standard Parcel Model for Canada Standard parcel editing model Standard parcel publishing model Leverages LGIM parcel model Canadian-izes survey legal descriptions Optional parcel dimension annotation First implementation in Oxford County Survey, ownership, assessment and easement parcels Condominium units as spatial entities Survey plan image mosaic

52 Canadian Parcel Data Model Many types of parcels Ownership, assessment, survey, easement, subsurface, zoning, lease

53 Canadian Parcel Data Model

54 Benefits to the Esri Canada Approach Lowers the risk of implementation Experienced implementation team - Subject matter expertise - Data migration experience - Deep product knowledge - Custom training solutions High quality Parcel Fabric The Canadian Parcel Data Model - Pre-configured parcel types, attributes, domains, and subtypes - Pre-configured display and symbology

55 Final Thoughts

56 Opportunities for engagement Our goal is to make you successful in your parcel mapping modernization There are varying levels of engagement: - Download the CPDM and implement the Parcel Mapping Solution yourself - Complete a Readiness Review with Esri Canada, then proceed with the Parcel Mapping implementation internally - Esri Canada can assist with the full implementation Different options depending on your needs Our recommendation: A readiness review on site will help position you for a successful implementation this is a great first step!

57 Final Thoughts There is an increasing demand for Parcel Mapping and a need for mapping modernization Capture> Join> Adjust methodology sets the ArcGIS Parcel Editing system apart from other systems Don t underestimate the complexity of migrating data into the Parcel Fabric help is available Experienced team of Parcel Mapping consultants on staff can offer guidance and expertise at various stages of a Parcel Editing implementation reach out to us!
