ArcGIS Desktop Parcel Editor : Fabric Adjustment

The ArcGIS® Parcel Fabric adjustment process, accessed via the Parcel Editor toolbar, uses a least-squares procedure with parcel dimensions treated as observations to derive positions for all points in a parcel boundary network. The Parcel Editor toolbar is available with ArcGIS Desktop (Standard and Advanced.) This paper explains the background, theory, and application of the least-squares method used to adjust parcel fabric data.

The ArcGIS® Parcel Fabric adjustment process is uniquely designed to test the integrity of a cadastral boundary network and to derive the most likely position for every point in the network. Part of that process uses a least-squares procedure with parcel dimensions treated as observations in a similar way to the adjustment of geodetic networks. This paper explains the least-squares adjustment process in mathematical detail. Equations used in computing the adjustment are given without derivation; however, references to the standard literature are provided. The primary purpose is to describe the background, theory, and application of the least-squares method used within the ArcGIS parcel fabric technology.
