Abstract

Estimating Accuracy of a City Wide Parcel Fabric
Track: Cadastral and Land Records
Authors: David Horwood, Amanda Chan

Accuracy of any GIS data is an elusive goal. Parcel Editing in ArcGIS with the parcel fabric provides tools to maintain and improve on the accuracy of parcel data, however does not provide statistical tools to quantify this accuracy. The City of Calgary now has a tool to fill this gap. The City can now visualize and quantify the inherent accuracy of their parcel fabric at any fabric point. The City is currently improving the accuracy of their fabric and producing a city wide accuracy heat map.
