Add a line event

Available with Pipeline Referencing license.

Characteristics of a route can be represented as a line event with start and end measure information along the route. Use the Add Line Event tool to add line events to the geodatabase.

ArcGIS Pipeline Referencing allows you to add events that span routes that are part of a line.

The example in the following workflow demonstrates adding a line event.

The following table details attributes for the routes (LA_Route1, LA_Route2, and LA_Route3) that belong to LineA:

Route ID	From Date	To Date
LA_Route1	1/1/2000	<Null>
LA_Route2	1/1/2000	<Null>
LA_Route3	1/1/2000	<Null>

1. Open the map in ArcGIS Pro and zoom to the location where you want to add the line event.
2. Click the Location Referencing tab, and in the Events group, click the Add drop-down menu and choose Add Line Event .

   The Add Line Event pane appears.

   

3. Click Next.

   The Route and Measure and Dates fields appear in the Add Line Event pane.

   

4. Click the Event Layer drop-down arrow and choose the line event layer.

   The Network layer is automatically populated once the event layer is chosen. 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.

5. If the selected event layer's parent network is a line network, click Choose line from map and choose a value to populate the Line Name text box.

   Alternatively, provide the line name in the Line Name text box.

6. Click Choose route from map to select the route on the map.

   Note:

   If a message regarding acquiring locks or reconciling appears, conflict prevention is enabled.

7. In the From: Route and Measure section, specify the start measure for the new line event along the route by doing one of the following to populate the Measure text box.
   • Click Choose measure from map and choose the start measure value along the route on the map.
   • Check the Use route start measure check box.
   • Provide the start measure value in the Measure text box.

   Note:

   After clicking Choose route from map or Choose measure from map , you can hover over the routes to see the route and measure at the location of the pointer.

   If only one applicable route exists at the edit location, click the location to select it. If multiple routes are applicable, click to choose one of the applicable routes using the Select Route dialog box.

   You can set map scale options for display of route and measure information on the Options dialog box, on the Location Referencing tab.

   A green point appears at the selected location on the map.

8. Optionally, in the To: Route and Measure section, specify the end measure for the new line event along the route by doing one of the following to populate the Measure text box:
   • Click Choose measure from map and choose the start measure value along the route on the map.
   • 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.

   You can also add events in the reverse direction of calibration of the route. For example, you can provide a start measure value greater than the end measure value for the events in the Add Line Event pane. The resulting events are created with the lesser value as the start measure, and the greater value as the end measure.

9. Specify the start date of the event by doing one of the following:
   • Click Calendar and choose the start date.
   • Provide the start date in the Start Date text box.
   • Double-click in the Start Date text box to use today's date.

   The start date default value is today's date, but you can choose a different date using the date picker.

10. 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.
    • Double-click in the End Date text box to use today's date.

    If no end date is provided, the event remains valid now and into the future.

11. Click Next.

    The Manage Attributes table appears.

    

12. Add event layer information using the attribute fields.

    Note:

    Coded values, range domains, subtypes, contingent values, and attribute rules are supported when configured for a field in an Attribute Value table.

13. Click Run.

    A confirmation message appears once the line event is added and appears on the map.

The following table details the spanning event after adding the line event:

Event	From Route ID	To Route ID	From Date	To Date	From Measure	To Measure	Location Error	MAOP Design Pressure
Event1	LA_Route1	LA_Route3	1/1/2000	<Null>	5	35	No Error	800
