Available with Location Referencing license.
Characteristics of a route, such as speed limit or functional class, can be represented as a line event by providing x-, y-, or optionally, z-coordinate locations as the basis for measure location. The coordinate data is stored as routes and measures.
The coordinates method appears as an optional method in the Add Line Event and Add Multiple Line Events tools. To add line events, choose the coordinates method and provide the x-, y-, and optionally, z-coordinates.
Add a line event by coordinates
To create a single line event by coordinates using the Add Line Event tool, complete the following steps:
- Open the map in ArcGIS Pro and zoom to the location where you want to add the line event.
- On the Location Referencing tab, in the Events group, click Add > Line Event
.The Add Line Event pane appears with the default Route and Measure value for From Method and To Method.
- Click the From Method drop-down arrow and choose Coordinates.
- Click the To Method drop-down arrow and choose Coordinates.
Using the Coordinates method, the measure location is based on geographic coordinates.
Tip:
You can use a combination of any of the methods to locate the start measure and end measure values. For example, you can use Route and Measure for the start measure value, and use Coordinates to define the end location on the map.
The methods you choose appear in the from and to section labels. For example, From: Route and Measure and To: Coordinates appear if the start method is Route and Measure and the end method is Coordinates.
- Click Next.
The Event Layer and Network options and the From: Coordinates and To: Coordinates sections appear in the Add Line Event pane.
- Click the Event Layer drop-down arrow and choose the event layer where the events will be added.
The parent LRS Network is populated based on the Event Layer value.
- Specify the route in the From: Coordinates section by doing one of the following:

Referent offset when using the Coordinates method
The Roads and Highways events data model supports the configuration of referent 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 line events are created using the Coordinates method in a referent-enabled layer, X/Y is used as the FromRefMethod and ToRefMethod field values, the geographic coordinates are used as the FromRefLocation and ToRefLocation field values, and the FromRefOffset and ToRefOffset fields are populated with 0.
The examples below demonstrate the impact of adding line event records that have referent values enabled.
Before adding a line event with referents
The following diagram shows Route1 before event creation:
The following table provides details about the route:
| Route ID | From Date | To Date |
|---|---|---|
Route1 | 1/1/2000 | <Null> |
After adding a line event with referents
The following diagram shows Event1 after event creation:
The following table provides details about the event referent fields in Event1 after event creation:
| FromRefMethod | FromRefLocation | FromRefOffset | ToRefMethod | ToRefLocation | ToRefOffset |
|---|---|---|---|---|---|
X/Y | 33.984980, -117.306397, 20 | 0 | X/Y | 33.965456, -117.265669, 20 | 0 |
The following table provides details about the default event record fields after event location:
| 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 values. If subsequent route edits are made, the RefMethod and RefLocation values revert to the parent LRS Network and the route, respectively.
Before adding multiple line events with referents
When events are created using the Coordinates method in a referent-enabled layer, X/Y is used as the FromRefMethod and ToRefMethod values, the geographic coordinates are used as the FromRefLocation and ToRefLocation values, and the FromRefOffset and ToRefOffset fields are populated with 0.

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 | FromRefOffset | ToRefOffset | Counter Peak Lanes |
|---|---|---|---|---|---|---|---|
Event1 | 1/1/2000 | <Null> | 12.64 | 14.91 | 0 | 0 | 3 |
Cracking Percent
| Event ID | From Date | To Date | From Measure | To Measure | FromRefOffset | ToRefOffset | Cracking Percent |
|---|---|---|---|---|---|---|---|
Event1 | 1/1/2000 | <Null> | 12.64 | 14.91 | 0 | 0 | 12 |
Directional Factor
| Event ID | From Date | To Date | From Measure | To Measure | FromRefOffset | ToRefOffset | Directional Factor |
|---|---|---|---|---|---|---|---|
Event1 | 1/1/2000 | <Null> | 12.64 | 14.91 | 0 | 0 | 100 |
Note:
If the route changes in subsequent edits, such as with reassignment, the RefLocation value changes as well.
You can edit the event using the attribute table so that it uses referents other than the default values. If subsequent route edits are made, the RefMethod and RefLocation values revert to the parent LRS Network and the route, respectively.
Retire overlaps scenarios
When the Retire overlaps check box is checked, 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 are created.
Merge coincident events scenarios
When the Merge coincident events check box is checked, the new event is merged with the existing event, and the measure range is expanded accordingly. The following conditions must be met:
- All attribute values of the new event are exactly the same as the existing event.
- The new event is adjacent to or overlapping an existing event in terms of its measure values.
- The new and existing events' time slices are coincident or overlapping.
