Displaying parcels using dimension vs. shape values
This topic applies to ArcEditor and ArcInfo only.
When opening and editing parcels in the projected map, you can choose to display parcel geometry using coordinates derived from the COGO dimensions on the parcel lines (including scale and rotation) instead of using the fixed, joined coordinate locations in the parcel fabric layer. When opening a parcel in the local coordinate frame, the parcel is always displayed using the COGO dimensions (including scale and rotation) on parcel lines. To edit parcels in the projected map rather than in a local coordinate system, leave the View and edit parcels individually in a local coordinate system option unchecked on the Parcel Editor Options dialog box.
When opening a parcel in the projected map, the parcel is displayed using the fixed, joined coordinates by default. To display the parcel using coordinates derived from COGO dimensions on the parcel lines, click the Parcel Editor arrow on the Parcel Editor toolbar and click Parcel Measurement View.
Displaying parcels using coordinates derived from the line's COGO dimensions is a useful way to check the correctness of the COGO dimensions. You will also see the scale and rotation of the parcel. If a bearing, distance, or curve parameter on a parcel traverse is incorrect or inaccurate, the error or inaccuracy will become visually apparent when the parcel is displayed using coordinates derived from these values. For example, in the graphics below, parcels displayed using coordinates derived from measurements are different from their display using their joined location coordinates.
When a parcel fabric is highly accurate and where COGO dimensions are consistent with their record values, there most likely will not be any noticeable differences between Parcel Measurement View and the view of a parcel in its fixed, joined location.
