Create a route

Disponible avec la licence Location Referencing.

Routes are created in an LRS Network using centerline features that define the location and geometry of a route.

The centerline features used to create routes can exist in the centerline feature class, be digitized into the centerline feature class (using aerial photography or other basemaps for guidance), be copied and pasted from other feature classes, or be imported from CAD files or other ArcGIS-supported data sources.

Remarque :

• When editing a network that supports lines, a new line is also created with the new route.
• The centerline and network feature classes must be present in the map to run this tool.
• An additional attribute table appears in the Create Route pane if your network feature class has extra fields. You can enter a route name here if your network is configured to use a user-generated route ID.
• Gap calibration rules are followed when creating routes.

1. Add the centerline and network feature class to a map.

   You can also open a map in which the centerline and network feature class are already present.

   Remarque :

   The information model expects only one centerline at any given location. Make sure that the centerlines used for your edit do not overlap other centerlines in your LRS.

   Remarque :

   Traditionally versioned networks must be edited through a direct connection to the geodatabase. Branch-versioned networks, including any network configured with a user-generated route ID, must be edited through a feature service.

2. Zoom in to the location where you want to create the route.

   The centerline features for the route must exist in the centerline feature class before creating the route.

   

3. On the Location Referencing tab, in the Routes group, click Create .

   

   The Create Route pane appears with the Select By Rectangle option selected by default.

4. Use your mouse to select one or more centerlines by rectangle at the location of the new route.

   You can also click the Select one or more centerlines drop-down arrow to choose one of the remaining selection tools: Select By Polygon , Select By Lasso , Select By Circle , Select By Line , or Select By Trace .

   Alternatively, you can use the interactive selection tools on the Map tab on the ArcGIS Pro ribbon:

   The selected centerlines are highlighted on the map and the Allow choosing of one or more centerlines button appears in the Create Route pane. The Selected Centerlines count is shown above the table.

   Remarque :

   • The direction of digitization determines the direction of calibration, increasing in the direction of digitization. You can reverse direction for the chosen centerlines using the Flip the direction of the centerlines button .
   • You can keep the centerlines chosen after creating the route.

   

5. Click the Allow choosing of one or more centerlines button .

   A table appears in the Create Route pane with each chosen centerline in a numbered row that corresponds to the selection order. Chosen centerlines are numbered on the map and highlighted. The Chosen Centerlines count is shown below the table.

   

6. Optionally, change the centerline selection order table by choosing one or more table rows and using the buttons below the table to reorder the selection. You can also drag rows into the desired order.

   Changes in the table selection order are also shown on the map.

   Tools available in the centerlines table

   Tool	Tool name	Tool description
   	Allow choosing one or more centerlines	Allows you to choose the centerlines in the map and displays them in a table by order of selection. Use the move buttons below the table or drag rows to reorder the chosen centerlines.
   	Clear the currently chosen centerlines	Clears the chosen centerlines and keeps the selected centerlines. You can reselect after clicking this button or click the Allow choosing one or more centerlines button a second time.
   	Move chosen centerlines up	Moves one or more selected centerlines up a row in the table order.
   	Move chosen centerlines to the top	Moves one or more centerlines to the top of the table order.
   	Move chosen centerlines down	Moves one or more centerlines down a row in the table order.
   	Move chosen centerlines to the bottom	Moves one or more centerlines to the bottom of the table order.
   	Flip the direction of the centerlines	Reverses the direction of the chosen centerlines.
   	Remove the chosen centerlines	Removes the chosen centerline from the table order but leaves it selected.

   Astuce :

   To change the display field shown in the centerlines table, right-click the centerline feature class in the Contents pane and choose Properties from the context menu. On the Layer Properties dialog box, click the Display tab, and click the Display field drop-down arrow to change its value. In the previous image, the display field is OBJECTID.

7. Choose the Network to which the new route will be added.

   Remarque :

   To edit using feature services, the LRS Network must be published with the linear referencing and version management capabilities.

8. You can create the route on a new line or an existing line.
   • To create the route on a new line, type the new line in the Line Name text box.
   • To create the route on an existing line, either type the name of an existing line or use the Choose line from map button to select an existing line from the map.
9. Provide a Route Name.

   The route name should be unique for the chosen network.

10. If you're creating a route on a network that supports lines, type a Line Name.

    The line name must be unique for the chosen network.

11. Click the Calendar button next to Start Date to choose a start date for the route.

    Astuce :

    You can also double-click the Start Date text box to automatically populate it with today's date, or type a date in the Start Date text box.

12. Type a value in the From Measure text box. The default is 0.000.

    If you don't know the From Measure value, you can do the following to calculate one by subtracting the geometrical length of the centerline from the To Measure value:

    1. Type a value in the To Measure text box.
    2. Click the Recalculate From Measure button next to the From Measure text box.
13. Update the To Measure value if necessary.

    Remarque :

    • Z-values are considered when calculating the geometric length of the centerlines.
    • Centerlines and routes support z-values.

    The To Measure value is automatically populated with the geometric length of the chosen centerline by default.

    Remarque :

    For the line network, the measures can be entered as station values in 00+00.00 or 00+00.000 format.

    If you don't know the To Measure value, you can do the following to allow Location Referencing to calculate one by calculating the count of the To Measure value and From Measure value:

    1. Update the From Measure value if necessary.
    2. Click the Recalculate To Measure button next to the To Measure text box.
14. Fill in additional field attributes in the network feature class as necessary.

    The attribute fields in the Create Route pane support coded value and range domains. This is helpful when you want to limit attribute values to a predefined list or range of values.

15. Click Run.

    The route is created, and calibration points are added at the ends of the route with the From Measure and To Measure values.

    Astuce :

    Click Identify Routes on the Location Referencing tab and select the new route in the map to view details about it.

    

    Astuce :

    You can keep the centerlines chosen after creating the route. This option is particularly useful if you're creating a route in the Engineering Stationing Network and want to create another one for the Continuous Network using the same centerlines, or vice versa. For more information, see Set Location Referencing options.

Complex route creation scenarios

The following sections provide examples of complex route creation, including loop, lollipop, branch, alpha, barbell, and infinity routes.

Create a loop route

In the following example, four centerlines (CL1, CL2, CL3, and CL4) are used to create a loop route.

Calibration points are added at the start of the loop (0), end of the loop (10), and at a third (3.33) and two-thirds of the loop (6.67).

Create a lollipop route

In the following example, two centerlines (CL1, CL2) are used to create a lollipop route.

RouteX is created with calibration points at the start of the stick portion (0), the end of the loop portion (12), and at a third (5.33) and two-thirds of the loop portion (8.67).

In the second example, two centerlines (CL1, CL2) with different directions compared to the example above are used to create a lollipop route.

RouteX is created with calibration points at the start of the loop portion (0), at a third (3.33) and two-thirds of the loop portion (6.67), and in the stick portion (12) at the end of the lollipop.

Create a branch route

In the following example, two centerlines (CL1, CL2) are used to create a branch route.

RouteX is created with calibration points at the start of the branch, the end of the branch, and at the start and end of an imaginary branch edge.

In the second example, two centerlines (CL1, CL2) are used to create a branch route.

RouteX is created with calibration points at the start of the branch, the end of the branch, and at the start and end of an imaginary branch edge.

Create an alpha route

In the following example, three centerlines (CL1, CL2, CL3) are used to create an alpha route.

RouteX is created with calibration points at the start (0) and end (16) of the alpha portion, and at a third (6.33) and two-thirds (9.67) of the loop portion.

Create a barbell route

In the following example, three centerlines (CL1, CL2, CL3) are used to create a barbell route.

RouteX is created with calibration points at the start (0) and end (18) of the barbell, and at a third (2.67 and 12.67) and two-thirds (5.33 and 15.33) of each loop portion.

Create an infinity route that starts and ends at an intersection

In the following example, one centerline (CL1) is used to create an infinity loop route that starts and ends at an intersection.

RouteX is created with calibration points at the start (0) and end (20) of the infinity route, and at a third (3.33 and 13.33) and two-thirds (6.67 and 16.67) of each loop portion.

In the following example, one centerline (CL1) is used to create an infinity loop that starts and ends on a loop.

RouteX is created with calibration points at the start (0) and end (10) of the infinity route, and at the middle (1.25 and 8.75) of every path from the base of the primary loop to each secondary loop. In this example, that is at a third (4.17) and two-thirds (5.83) of the secondary loop.

A route in a Utility Network dataset

The centerlines (pipeline layer) involved in creating a route in the Utility Network dataset must have their from measure and to measure fields populated with measure values.

Remarque :

Use the Configure Utility Network Feature Class tool to associate the pipeline layer, and the Update Measures From LRS tool to populate measure values.

When multiple centerlines are used, the coincident points of the centerline features must have the same measures. The from measure and the to measure of the route are populated using these measure values.

In the following example, the coincident points of the centerlines match. The to measure of CL1 matches the from measure of CL2 (14). In this case, a route can be created.

RouteX is created from CL1 and CL2. Calibration points are created at the ends of each centerline.

In the following example, the coincident points of the centerlines do not match. The to measure of CL1 does not match the from measure of CL2 (16, 14). In this case, a route cannot be created.

In the following example, the coincident points of the centerlines match, but the from measure and to measure of CL2 are the same (19). A route cannot be created because it would be nonmonotonic.
