About using connection lines to improve parcel fabric connectivity

This topic applies to ArcEditor and ArcInfo only.

The parcel fabric needs to be well connected for a fabric least-squares adjustment to run successfully. A well-connected fabric improves network redundancy, which leads to more reliable results from the fabric least-squares adjustment.

You can use the Create Connection tool located on the Parcel Editor toolbar to add connection lines in the parcel fabric.

For a fabric least-squares adjustment to run successfully, the parcel fabric network needs to be well connected. The Create Connection tool can be used to quickly add connection lines between blocks of parcels without having to open and edit the parcels themselves. For example, a fabric least-squares adjustment does not run if an island of parcels is not well connected to the surrounding parcel fabric.

Connection lines connecting parcel blocks

Connectivity is also established from common center points of curves.

Connectivity from radial lines

Line points

In some cases, parcel blocks are connected through line points. Since line points sit or float on top of adjacent parcel lines, connectivity is insufficient, and the fabric least-squares adjustment will fail.

In the graphic below, adjacent parcels share no common points. Parcel points are line points that sit on the adjacent parcel boundaries and do not split the boundaries. Because no common points are being shared, these parcels are effectively floating next to each other and are not connected. For a fabric least-squares adjustment to run on these parcels, connection lines may need to be added between parcel corners. Connection lines can sit on top of parcel boundary lines.

Adjacent parcels are only connected through line points.
