In GeoSTORM software, the Renumber Interconnected Roadway Segments command allows the user to automatically renumber roadway segments and the connected routing junctions and catch basin inlets along a defined flow path.
Follow the steps below to use the Renumber Interconnected Roadway Segments command:
- From the Input ribbon menu, click on the Roadway Gutter/Ditch/Inlets dropdown menu and then select the Renumber Interconnected Roadway Segments command.

- The Renumber Interconnected Roadway Segments dialog box will be displayed, as shown below.

The following sections describe how to use the Renumber Interconnected Roadway Segments command and interact with the above dialog box.
Selecting Roadway Segments
The Select Roadway Segments panel allows the user to select roadway segments that define the pipe path.
Selecting Multiple (Interconnected) Roadway Segments
The Select Multiple (Interconnected) Roadway Segments section is used to sequentially number roadway segments and routing junctions along the selected path that has roadway segments connected end-to-end with each other.
Click the [Pick] button to manually select roadway segments from the Map View. The Renumber Interconnected Roadway Segments dialog box will temporarily disappear, allowing the user to select the downstream most and upstream most roadway segments from the Map View. Once finished, press the [Enter] key or right-click and choose Done from the displayed context menu. The dialog box will be redisplayed, and the total number of selected roadway segments will be shown in the Total selected read-only field, as shown below.
Alternatively, if roadway segments are pre-selected on the Map View, opening the Renumber Interconnected Roadway Segments dialog box will show those roadway segments selected in the corresponding table section. The selected roadway segments can be further unselected by unchecking the checkboxes corresponding to them.
Note that the user can pre-select multiple roadway segments from the Map View by pressing and holding down the [Ctrl] key while selecting the roadway segments.
Manual Editing
This section contains a table that displays the selected roadway segments, routing junctions, and their associated data. The values in the New Roadway Segment ID and New Routing Junction ID columns provide a preview of the renumbered roadway segments and routing junctions defined in the Roadway Segment Renumbering and Routing Junction Renumbering panels.
The data contained in the table can be copied to the clipboard or exported as a Microsoft Excel or PDF document by using the Copy Table to Clipboard, Export Table to Excel, or Export Table to PDF commands of the right-click context menu.
Roadway Segment Renumbering
The Roadway Segment Renumbering panel allows the user to renumber roadway segments based on roadway segment length or sequentially. By default, the checkbox on this panel is checked. If unchecked, then the content of this panel will be disabled (i.e., grayed out) and the renumbering of roadway segments cannot be performed.
The following options are provided in this panel:
- Roadway segment ID prefix: This optional checkbox entry allows a prefix to be added to the roadway segment ID.
- Roadway segment ID suffix: This optional checkbox entry allows a suffix to be added to the roadway segment ID.
- Roadway segment ID preview: This read-only field provides a preview of the roadway segment ID defined in this panel.
- Numbering direction: This dropdown combo box allows the user to select the flow direction in which the roadway segment IDs can be renumbered. The following options are available:
- Upstream
- Downstream
Use Auto Increment
The Use auto increment subsection allows the user to renumber roadway segments using a fixed increment. Select the Use auto increment radio button option to enable this subsection.
The following options are provided in this subsection:
- Roadway segment ID digits: This entry field allows the user to set the number of digits to be used for roadway segment For example, using 3 digits causes the roadway segment ID to be of the format 001, 002, and 003.
- Next available roadway segment ID: This entry field defines the next roadway segment ID number to be used.
- Roadway segment ID increment: This entry field defines the increment to use when numbering roadway segments. The default value is 1.
Use Roadway Segment Length
The Use roadway segment length subsection is used to renumber roadway segments based on their length along the defined pipe path. By default, the Use roadway segment length radio button option is selected when the Roadway Segment Renumbering panel is checked.
The following options are provided in this subsection:
- Upstream roadway segment ID: This entry provides a roadway segment ID that will be used as the upstream most roadway segment number.
Note that if the Downstream option is selected in the Numbering direction dropdown combo box, then the Downstream roadway segment ID entry will change into the Upstream roadway segment ID, as shown below.

- Distance units: This dropdown combo box defines the unit of roadway segment length. The available options are:
- Feet
- Miles
- Decimal precision: This optional checkbox entry defines the decimal precision that will be used in renumbering roadway By default, this checkbox is unchecked. If checked, then the user can enter a value ranging from 0 to 15.
After defining all the required data in this panel, click the [Preview] button to preview the IDs of the renumbered roadway segments in the New Roadway Segment ID column of the Manual Editing table, as shown below.
Routing Junction Renumbering
The Routing Junction Renumbering panel allows the user to renumber routing junctions based on roadway segment length or sequentially. By default, the checkbox on this panel is checked. If unchecked, then the content of this panel will be disabled (i.e., grayed out) and the renumbering of routing junctions cannot be performed.
The following options are provided in this data panel:
- Routing junction ID prefix: This optional checkbox entry allows a prefix to be added to the routing junction ID.
- Routing Junction ID suffix: This optional checkbox entry allows a suffix to be added to the routing junction ID.
- Routing junction ID preview: This read-only field provides a preview of the routing junction ID defined in this panel.
- Numbering direction: This dropdown combo box allows the user to select the flow direction in which the routing junction IDs can be renumbered. The following options are available:
- Upstream
- Downstream
Use Auto Increment
The Use auto increment subsection allows the user to renumber routing junctions using a fixed increment. Select the Use auto increment radio button option to enable this subsection.
The following options are provided in this subsection:
- Routing junction ID digits: This entry allows the user to set the number of digits to be used for the routing junction ID. For example, using 3 digits causes the routing junction ID to be of the format 001, 002, and 003.
- Next available routing junction ID: This entry field defines the next routing junction ID number to be used.
- Routing junction ID increment: This entry field defines the increment to use when numbering routing junctions. The default value is 1.
