Merge Street Subsegments

The Lucity GIS Edit tools include a tool used for merging subsegment features in the geodatabase and in the desktop.

Note: The Subsegment Merge Tool is only enabled if all of the following conditions are met: (1) Two features are selected in the map (2) The features selected are linear (3) The features are snapped together at one end

How To Merge two subsegments in the map

1. In ArcMap, start an edit session.
2. Select two adjacent subsegment features in the map that are part of the same street segment. This is done by dragging a box around the two conduits or by clicking on one conduit and then holding down the SHIFT key while clicking on the second conduit.
3. Click the Subsegment Merge tool on the Lucity GIS Edit toolbar.

   

4. The merge tool requires that edits be saved before and after performing the merge. One of the following prompts will appear asking to proceed.

   

   

5. Click Yes and the following dialog will appear.

   

• Existing From Subseg: This is read-only information about the pre-merged from subsegment.
• Existing To Subseg: This is read-only information about the pre-merged to subsegment.
• Merged Subseg: These fields will be automatically populated based upon the existing subsegment information. This information can be manually overwritten.
  • The sidewalk length fields are calculated by the system based on:

    [(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.
• New Subsegment Attributes-Copy from: Users can choose to copy over the attributes from the pre-merged from subseg, pre-merged to subseg, or the longer subsegment. Note: This option will be automatically set and disabled if the new street segment ID is the same as the previous to or from street segment ID.

1. After making all selections, click OK.
2. The following message will appear when the process is finished.
