Spatial Alignment Resources

Data Alignment Workflow Package

The Data Alignment Workflow Package (DAWp) is a collection of ArcGIS Desktop based workflows, available for ParcelMap BC users to assist with initial and ongoing alignment of data sets. The DAWp was developed in conjunction with Esri Canada. Tutorial Videos for the DAWp are available to help guide implementation.

The DAWp supports both Initial Alignment (Rubbersheet & Fabric Shift methods) and Ongoing Alignment (Analyze Fabric Shift’ tools that creates fabric shift links and the ‘Realign Features’ Add-In) only in ArcMap.
If your organization has moved to ArcGIS Pro, and you wish to perform Ongoing Alignment, please use the Fabric Spatial Improvement Product with the Rubbersheet Features tool. This an out of the box tool, but it requires an Advanced level license.

• Tips and Tricks for using the DAWp

  Includes questions initially raised by users during the Data Alignment Workflow Package (DAWp) Pre-Release Feedback Web Session on April 29th, 2020. The responses were provided by Sarah Sibbett (Senior Consultant – Esri Canada) and compiled into these guidelines for use by the broader ParcelMap BC adopter community. This document may be revised from time to time as new guidelines are added based on feedback from the community.

ICI Society Virtual Café: ParcelMap BC Spatial Alignment Workshop - June 24th, 2021 Video Recording

(Length 1hr:57min): The theme of the workshop was the presentation by Esri Canada on the usage of the Data Alignment Workflow Package (DAWp) with an emphasis on the Situation Assessment, Initial Alignment and Ongoing Alignment steps. Other topics included:

• Spatial Alignment Resources: Why & what are they?
• Adoption Transition Steps: Transition Project Management Guide
• Transition Project Management Guide -WBS
• Understanding ParcelMapBC Spatial Improvements - Why, Where and When is ParcelMapBC spatially improved?
• Spatial Improvement Assessment App & Map Layers
• Cadastral Ties Submission for Spatial Improvements
• Context: Where do the Alignment Tools “Fit” during Transition?
• Case Study –“Anytown” - Use Cases for the DAWp as part of the ParcelMapBC Transition Workflow
• User Experience with DAWp – Township of Langley
• Accessing ParcelMapBC Spatial Alignment Resources

A PDF version of the PowerPoint Presentation is available.

ArcGIS Pro2.7 Parcel Alignment Demo

Esri Parcel Fabric Meetup video - a demo by Esri Inc using data from the City of Kelowna to illustrate the parcel alignment workflow using the ArcGIS Pro2.7 tools to: 1) Generate fabric links and anchor points 2) Rubber sheet using the generated links and anchor points to align data. The example shows how the exported shift vector data from ParcelMap BC can be used by organizations to align their parcel data to ParcelMap BC. Starts at 31:30 on the video time slide.

Cadastral Ties Submission Guidelines for Spatial Improvements

ParcelMap BC generally relies on new survey data including ties to known control provided in survey plan datasets to improve the spatial accuracy of the mapped representation. To provide additional inputs for spatial improvements, the ParcelMap BC Operations Team has defined submission guidelines for organizations to submit cadastral ties captured outside legal survey plans. Examples include infrastructure or construction surveys tied to legal boundaries which local governments and utilities may capture as part of their operations.

These guidelines can be used to submit new points to augment the level of control and help improve the mapping in areas which would have been otherwise challenging to update.

Submitted cadastral ties will be evaluated by the ParcelMap BC Operations Team to determine:

1. If the cadastral tie is suitable to be included in ParcelMap BC. For example, a submitted tie will not be included if:

   A.	The ties are captured using a means providing less confidence in absolute accuracy than suitable – examples include consumer grade GPS or unverified offsets.
   B.	Duplicate cadastral ties already exist in the fabric.

2. When a suitable cadastral tie may be used the ParcelMap BC Operations Team to conduct spatial improvements.

If your organization is interested in submitting cadastral ties to ParcelMap BC, please contact parcelmapbc@ltsa.ca to receive a detailed guide and worksheet template on the attribution required for submission.
