Merge Street Subsegments

The Subsegment Merge tool, which is located on the Lucity GIS Edit toolbar, enables users to combine subsegment features in the geodatabase and in Lucity.

This tool is enabled only when: 1) two features are selected in the map; 2) both are linear; and 3) they are snapped together at one end.

How To Merge Two Subsegments in the Map

1. Start an edit session in ArcMap.
2. Select two adjacent Subsegment features in the map that are part of the same Street Segment by either dragging a box around them or by clicking on one subsegment and then holding down the SHIFT key while clicking on the second.
3. Click the Subsegment Merge tool on the Lucity GIS Edit toolbar.

   

4. The Subsegment Merge tool requires the system to save edits before and after performing the merge. When prompted to confirm the save (examples below), click Yes.

   

   

5. The Street Subsegment Merge form appears. The two sections at the top of the form display information about the Subsegments being merged.

   

   The fields in the Merged Subsegment section display the attributes of the new Subsegment, which are based upon the existing Subsegments' data. The user can overwrite these fields.

   • Sidewalk Length fields are calculated as:

     [(Old Sidewalk Length 1+ Old Sidewalk Length 2)/(Old Subsegment Length 1 + Old Subsegment Length 2)] x New Subsegment Length]

   • Driveway Approach fields are calculated using the same logic.
6. In the New Subsegment Attributes-Copy from section, choose whether to copy attributes from:
   • the longer Subsegment,
   • the pre-merged From Subsegment, or
   • the pre-merged To Subsegement.

     Note: This option is automatically set/disabled if the new Street Segment ID is the same as the previous To or From Street Segment ID.

7. After making all selections, click OK. The following message appears when the process is complete:
