The Add Point Event widget allows you to create point events along routes in a Linear Referencing System (LRS). You can use the widget to manage pipeline data with ArcGIS Pipeline Referencing and roadway data with ArcGIS Roads and Highways. You can represent characteristics of a route, such as inline inspection (ILI) survey readings for a pipeline or speed limit signs for a road, as single point events with measure information along the route.
Note:
All Location Referencing widgets support express mode. When you create an app in express mode, all Location Referencing widgets are automatically configured based on the web map added to the Map widget. Any modifications made in the Map widget, such as changing the web map, will instantly be reflected in the Location Referencing widgets. Express mode allows you to efficiently set up Location Referencing widgets within ArcGIS Experience Builder, streamlining the deployment process for apps that contain Location Referencing widgets.
Examples for Pipeline Referencing
Use this widget to support app design requirements such as the following:
- You want to add anomaly information along a route.
- You want to add anomaly, inspection note, and documentation point information along a route in a single operation.
- You want to add event data to pipeline routes by entering station numbers, where the station measure values are used to calculate route and measure values for events.
Examples for Roads and Highways
Use this widget to support app design requirements such as the following:
- You want to add crash information along a route.
- You want to add stop sign, reference post, and bridge point information along a route in a single operation.
- You want to add event data to highway routes by entering station numbers, where the station measure values are used to calculate route and measure values for events.
Usage notes
This widget requires connection to a Map widget. To add point events, the Map widget must be connected to a web map data source with an LRS published with the Linear Referencing and Version Management capabilities enabled.
To create an LRS and publish a feature service with the Linear Referencing and Version Management capabilities enabled, follow the steps in the ArcGIS Pro documentation:
- Pipeline Referencing—Create an LRS and share an LRS as web layers
- Roads and Highways—Create an LRS and share an LRS as web layers
To use the Add Point Event widget with feature services published with ArcGIS Enterprise, you must be signed in with an ArcGIS Enterprise account.
When you include this widget in an app, a panel provides users with the following parameters for adding a point event:
- Type—Choose to add single or multiple point events.
- Single Point—Add a single point event.
- Multiple Point—Add multiple point events in one edit activity.
- Event (appears when you choose Single Point under Type)—Choose the event layer from which to add a point event.
- Network—This parameter lists the network layer associated with the selected event.
- Attribute Set (appears when you choose Multiple Point under Type)— Attribute sets are collections of event layer attributes. If a layer is configured with attribute sets for Pipeline Referencing or attribute sets for Roads and Highways, you can choose one from the drop-down menu. The widget only displays point events that are part of the attribute set. You can use attribute sets to create multiple events with a set of additional, organization-specific attributes in a single edit.
- Method—The method the widget uses to specify the location of the point events to be added is listed here.
- Route and Measure—Add a point event to a route using a specific measure.
- Route ID or Route Name—Provide a route ID or name for the route where you want to add a point event. If the network layer has route name configured as an identifier, this setting is labeled Route Name.
- Measure—Provide a measure value. The measure value defines the exact location on the route where the added event will be located. The label for this setting also displays the unit of measure defined by the network layer. For example, if the unit of measure is meters, this setting is labeled Measure (Meters) at run time.
- Route and Measure—Add a point event to a route using a specific measure.
- Start Date—Specify the start date of the event or events.
- End Date—Specify the end date of the event or events.
- Add event to the dominant route—Add events to the dominant route where route concurrencies exist.

Add a point event by route and measure
Complete the following steps to add a point event using the Route and Measure method.
- Start Experience Builder. Sign in to an ArcGIS Enterprise portal.
- Add a Map widget. Connect it to a web map with LRS data published with the Linear Referencing and Version Management capabilities enabled.
- Add an Add Point Event widget. Connect it to the Map widget, and load LRS layers from the Map widget.
- Publish the app.
- Launch the app. If prompted, sign in to your ArcGIS Enterprise portal.
- Zoom to the location where you want to add a point event.
Note:
To zoom to route locations, you can use the Search By Route widget or use data actions with the Search By Route widget or Table widget. - Open the Add Point Event widget.
The first image is an example of the Add Point Event widget panel with Roads and Highways data. The second image is an example of the Add Point Event widget panel with Pipeline Referencing data. - Use the default type or click the Type drop-down arrow and change the type, if necessary.
- If Type is set to Single Point, use the default point event layer or click the Event drop-down arrow and choose another point event layer.
The value that appears under Network is based on the selected event layer.
- If Type is set to Multiple Point, use the default attribute set or choose another attribute set.
- If there are multiple methods configured in the widget settings, choose Route and Measure from the Method drop-down menu.
- Specify a route by doing one of the following:
- Provide a route ID or name in the Route ID or Route Name text box.
- Click the route picker
, and click a route on the map.The Measure value populates based on the location you click.
- Specify a location for the point event by doing one of the following:
- Provide a measure value in the Measure text box.
Note:
Stationing measure values are also supported.
- Click the measure picker , and click a point along the route.
Once you provide a measure value, a green point appears at that location on the map.
- Provide a measure value in the Measure text box.
- Specify the start date of the event by doing one of the following:
- Leave the default start date, which is the current date.
- Provide a start date in the Start Date text box.
- Click the calendar button
and choose a start date. - Check the Use route start date check box.
- Optionally, specify the end date for the point event by doing one of the following:
- Provide an end date in the End Date text box.
- Click the calendar button and choose an end date.
- Check the Use route end date check box.
Note:
If you do not provide an end date, the event remains valid from the route start date into the future.
- If route concurrencies exist, you can add point events to the dominant route.
Concurrent routes are routes that share the same centerlines. This relationship may exist to model two routes with different directions of calibration. Where these concurrent routes exist, you can use a set of rules to choose a route that's considered dominant.
For example, in the diagram below, there are two routes with route IDs 100 and 200.
The route dominance rule is set such that the greater the route ID, the more dominant the route. Using this condition, Route 200 is the dominant route, and Route 100 is the subordinate route.
When adding point events at two locations on Route 100, the event will be added to Route 100 at location 1 because no other route exists at that point. At location 2, Route 200 has a greater order of dominance, so the event will be added to Route 200.
