Merge Street Segments

The Street Merge tool is used to merge two street segments in the geodatabase and in Lucity.

The Street Merge 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 Street Segments in the Map

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

   

4. The 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 Segment Merge form appears. The three sections at the top of the form display information about the two Streets being merged and the related Intersection.

   

6. In the top-center box (Existing Intersection), choose how you want the system to handle the feature following the merge. (This field is enabled if an intersection is located at the common endpoint of the selected street features.)
   • Don't Delete Feature: Retains the Intersection in both the Desktop Inventory module and in the intersection feature class.
   • Delete Feature From GIS Only: Retains the Intersection in the Desktop Inventory module, but removes it from the intersection feature class.
     Note: This option is disabled if the tool cannot locate an Intersection within one map unit of the common End Point for the two Streets or if the intersection feature class is not editable.
   • Delete from GIS and Lucity: Removes the Intersection from both the Desktop Inventory module and the intersection feature class.
     Note: This option is disabled if the tool cannot locate an Intersection within one map unit of the common End Point for the two Streets, the intersection feature class is not editable, or the Intersection doesn't exist in the Desktop Inventory module.
   • Structure Status: If the Intersection is to be retained in the Desktop Inventory, select a Status.
7. In the New Street Segment section, choose whether to:
   • Manually enter a New Segment ID,
   • Use the Lucity Auto Number function (enabled only when an Segment ID field in the feature class uses a number-generator),
   • Use the End Point IDs,
   • Use the Existing Segment ID of the To Street, or
   • Use the Existing Segment ID of the From Street.
8. At the bottom of the New Street Section box, choose whether to enable the Merge Subsegments option. (This option is enabled by default if both street segments have only a single associated subsegment.) Leave the option checked to maintain a one-to-one ratio between street segments and subsegments; uncheck it if you prefer the merged street segment to have two subsegments.
9. In the New Street Segment Length section, choose how the system should treat any difference in the Street Segment Length between Lucity and GIS (enabled only when such a difference exists):
   • Set Lucity Length = GIS Length or
   • Use Lucity-Calculated Length.
10. In the New Street Segment Attributes-Copy from section, choose whether to copy the merged Street's attributes from:
    • the Longer Street,
    • the Existing From Street (pre-merge), or
    • the Existing To Street (pre-merge).

      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.

11. After making all selections, click OK. A message appears to notify the user that the process is finished.
