Introduction to Parcel Fabric Amir Plans Parcels Control 1 Points 1-1 Line Points - Lines Editing and Maintaining Parcels using Deed Drafter and ArcGIS Desktop
What is a parcel fabric? Dataset of related tables and feature classes - 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 Editing and Maintaining Parcels using Deed Drafter and ArcGIS Desktop

What does a Deed Examiner do? Receive new deeds Enter the measurements and decide if deed modifies the existing parcel geometry or not (straight transfer) If it does modify parcel geometry the deed is sent to be entered again by the Assessor map technician, public works, zoning ArcGIS Deed Drafter: An Introduction
We can do better Efficiency: avoid duplicate data entry by the map technicians Up to date: The recorder needs to work against the most current data ArcGIS Deed Drafter: An Introduction

Least Square Adjustment Amir Editing and Maintaining Parcels using Deed Drafter and ArcGIS Desktop
Accuracy Types of accuracy in parcel data: - Attribute data - Topological - Spatial accuracy (ground truth) - Relative accuracy
Accuracy Indicator 1 Parcel Level Attribute data correct dimensions Data entry, parcel misclose Measurement view
Accuracy Indicator 2 Topological Integrity Joining process: rotation & scale Control Points Check fit
Accuracy Indicator 3 Least Squares Adjustment
Parcel Editor Adjustment Type Fabric Adjustment - using Weighted Least Squares Adjustment Associated Features Adjustment for features that rely on parcels Legacy reference Lines (blue)
Fabric adjustment Uses survey control points Uses lines measurements (COGO ) attributes and weights Improves spatial accuracy of parcel corners Finds mistakes/blunders in parcel data Can help indicate where additional control is needed in the network Dimensions are NOT changed Only parcel point coordinates are updated
Fabric Adjustment- Best Practices Line categories and Anatomy of a Parcel Use of line Weights Choice of Control Ground-to-grid Close points and Line-points Parcel Fabric networks vs GPS Baseline networks Convergence and Divergence Adjusting the Whole Fabric
Line Weights Parcel line weights: - 1 Highest - 2 After 1980-3 1908 to 1980-4 1881 to 1907-5 Before 1881-6 1800-7 Lowest Accuracy category 7 For limited use; never assign at the parcel or plan level Ignored by the adjustment, can create holes if too many
Line Weights a Hierarchy A weight category on a line is optional - Weight overrides the plan s & parcel s A weight category on a parcel is optional - Weight overrides the plan s A weight category on the plan is required - the default when no weight on parcel or line Most typical scenario - all lines and parcels in plan have null weights - plan s weight used, assumes plan defines data in the same survey Plans Parcels Lines
Close points and Line-points Close points - Points within a tolerance that have no line between them - These points should be merge, UNLESS they are radial points where the radial lines are longer than 50 meters Line points - Applied when co-linear lines overlap a longer line - Used to keep overlapping parcel line geometry coincident
Convergence and Divergence Run adjustment more than once - no automatic iteration Convergence is the goal - maximum coordinate shift remains at 0.00 in 2 successive adjustments Divergence - adjustment fails - the adjustment may succeed the first few times, but then fails on the next run - Analyze adjustment results to find the problem
Adjusting the Whole Fabric Limit is 50K points per adjustment Technique of overlapping adjustment areas - -predefine partial overlap areas that share some common control within the area of overlap - Each adjustment is analyzed & converges - (Future) GP tool runs each pre-defined adjustment area as a batch process, problems logged to a file Useful for epoch changes - control points are updated - Re-run the pre-defined adjustments as a batch process
