Characteristics of a route can be represented as a line event with start and end measure information along the route. Use the Add Multiple Line Events tool to add multiple line events at the same time.
Add multiple line events scenario
The example in the following workflow demonstrates adding multiple line events.
The following diagram shows the route attributes. The route (Route1) has measures from 12 to 15.
The following table provides details about the route attributes:
Route ID | From Date | To Date |
---|---|---|
Route1 | 1/1/2000 | <Null> |
Add multiple line events by route and measure
Complete the following steps to add multiple line events by route and measure:
- Open the map in ArcGIS Pro and zoom in to the location where you want to add the line events.
- Click the Location Referencing tab, and in the Events group, click Add > Multiple Line Events .
The Add Multiple Line Events pane appears with the Route and Measure default value as the From Measure and To Measure values.
Using the Route and Measure method, the measure location is based on the measure values from the selected route.
- Click Next.
The From: Route and Measure, To: Route and Measure and Dates sections appear in the Add Multiple Line Events pane.
- Click the Network drop-down arrow and choose the LRS Network of the route where you want to add line events.
The network serves as the source linear referencing method (LRM) to define the input measures for the event.
The network is an LRS Network published as a layer in the feature service.
- In the From: Route and Measure section, click the Choose route from map button and click the route on the map.
Alternatively, provide the route ID in the Route ID text box.
Note:
After clicking the Choose route from map button or the Choose measure from map button , you can hover over the route to see the route and measure at the location of the pointer.
You can set map scale options for the display of route and measure information on the Options dialog box, on the Location Referencing tab.
Note:
If a message regarding acquiring locks or reconciling appears, conflict prevention is enabled.
- In the From: Route and Measure section, specify the start measure for the new line events along the route by doing one of the following to populate the Measure text box:
- Click Choose measure from map and click the route on the map where you want the start measure placed.
- Check the Use route start measure check box.
- Provide the start measure value in the Measure text box.
A green point appears at the selected location on the map.
- In the To: Route and Measure section, specify the end measure for the new line events along the route by doing one of the following to populate the Measure text box:
- Click Choose measure from map and click the route on the map where you want to place the end measure value.
- Check the Use route end measure check box.
- Provide the end measure value in the Measure text box.
A red point appears at the selected location on the map.
The new events are created between the green and red dots.
- Specify the start date of the line events by doing one of the following:
- Provide the start date in the Start Date text box.
- Check the Route start date check box.
- Double-click in the Start Date text box to use today's date.
- Optionally, specify the end date of the event by doing one of the following:
- Click Calendar and choose the end date.
- Provide the end date in the End Date text box.
- Check the Route end date check box.
- Double-click in the End Date text box to use today's date.
If no end date is provided, the event remains valid from the start date into the future.
- Choose a data validation option to prevent erroneous input while characterizing a route with line events.
- Retire overlaps—The measure, start date, and end date of existing events are adjusted to prevent overlaps with respect to time and measure values once the new line event or events have been created. Refer to the retire overlaps scenarios for more examples.
- Merge coincident events—The new event is merged with the existing event and the measure range is expanded accordingly when all attribute values for a new event are exactly the same as an existing event, and if the new event is adjacent to or overlapping an existing event in terms of its measure values, and its time slices are coincident or overlapping. Refer to the merge coincident events scenarios for more examples.
- Click Next.
Manage Attributes appears in the pane with the default attribute set in the Attribute Set drop-down list.
The Attribute Set drop-down list includes other attribute sets if configured.
- Optionally, choose an attribute set from the Attribute Set drop-down list.
- Provide attribute value information for the events in the attribute set.
Note:
Click Copy attribute values by selecting event on the map and click an existing line event belonging to the same event layer on the map to copy event attributes from that event.
- Click Run.
A confirmation message appears once the line events are added and appear on the map.
The following tables provide details about the line events by event layer:

The following diagram shows the route and the associated line events on Route1 from 12 to 15 after the edit:
Referent offset when using the route and measure method
The Roads and Highways events data model supports the configuration of referent event fields and their enablement using the Enable Referent Fields tool. Once referent fields are configured and enabled in a layer, referent locations are populated and persisted in that layer when events are added or edited.
When events are created using route and measure in a referent-enabled layer, the parent LRS Network is used as the FromRefMethod and ToRefMethod values by default, and the route is used as the FromRefLocation and ToRefLocation values. The from and to measures of the new line events are used as the FromRefOffset and ToRefOffset values.
If either measure of a line event is updated, the corresponding offset value updates to reflect the new measure.
The examples below demonstrate the impact of adding multiple line events that have referent values enabled.
Before adding multiple line events with referents
The following diagram shows the routes before event creation:
The following table provides details about the routes:
Route ID | From Date | To Date | From Measure | To Measure |
---|---|---|---|---|
Route1 | 1/1/2000 | <Null> | 12 | 15 |
The following table provides details about the event referent fields before event creation:
FromRefMethod | FromRefLocation | FromRefOffset | ToRefMethod | ToRefLocation | ToRefOffset |
---|---|---|---|---|---|
<Null> | <Null> | <Null> | <Null> | <Null> |
After adding multiple line events with referents
The following diagram shows multiple line events that have referents enabled:
The following table provides details about the event referent fields after event creation:
FromRefMethod | FromRefLocation | FromRefOffset | ToRefMethod | ToRefLocation | ToRefOffset |
---|---|---|---|---|---|
AllRoutes | Route1 | 12.64 | AllRoutes | Route1 | 14.91 |
The following tables provide details about the default event fields after event creation:
Counter Peak Lanes
Event ID | From Date | To Date | From Measure | To Measure |
---|---|---|---|---|
Event1 | 1/1/2000 | <Null> | 12.64 | 14.91 |
Cracking Percent
Event ID | From Date | To Date | From Measure | To Measure |
---|---|---|---|---|
Event1 | 1/1/2000 | <Null> | 12.64 | 14.91 |
Directional Factor
Event ID | From Date | To Date | From Measure | To Measure |
---|---|---|---|---|
Event1 | 1/1/2000 | <Null> | 12.64 | 14.91 |
You can edit the event using the attribute table so that it uses referents other than the default. If subsequent route edits are made, the RefMethod and RefLocation values revert to the parent LRS Network and the route, respectively.
Retire overlaps scenarios
