Add line events by coordinates

Available with Location Referencing license.

Characteristics of a route pipeline, such as DOT Cass or Test Pressure Range, 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

Complete the following steps using the Add Line Event tool to create a single line event by coordinates:

  1. Open the map in ArcGIS Pro and zoom to the location where you want to add the line event.
  2. On the Location Referencing tab, in the Events group, click the Add > Line Event Add a single line event.

    The Add Line Event pane appears with the default Route and Measure value.

  3. Click the From Method drop-down arrow and choose Coordinates.
  4. Click the To Method drop-down arrow and choose Coordinates.

    Using the Coordinates method, the measure location is based on geographic coordinates.

    Add Line Event pane
    Tip:

    You can use a combination of any of the methods to locate the from measure and to measure values. For example, you can use Route and Measure to choose the from measure value, and use Coordinates to define the to 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 from method is Route and Measure and the to method is Coordinates.

  5. Click Next.

    The Event Layer and Network options and the From: Coordinates and To: Coordinates sections appear in the Add Line Event pane.

  6. 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.

  7. If the parent LRS Network is a line network, specify the name of the line feature by doing one of the following:
    • Type a line name in the Line Name text box.
    • Click Choose line from map Choose line from map and click the line on the map.

    The line is highlighted in light blue.

  8. Specify the route in the From: Coordinates section by doing one of the following:
    • Type the route name in the Route Name text box.
    • Click the Route Name drop-down arrow and choose the route.
    • Click Choose route from map Choose route from map and click the route on the map.

    The specified route is highlighted in light blue.

    Note:

    If a message appears that is related to acquiring locks, the need to reconcile, or not being able to acquire locks, Pipeline Referencing conflict prevention is enabled.

  9. Optionally, in the From: Coordinates section, provide a geographic coordinate factor value in the GC Factor text box.
  10. In the From: Coordinates section, click the Spatial Reference drop-down arrow and choose a spatial reference.
    • LRS Spatial Reference—The spatial reference of the LRS network
    • Web Map Spatial Reference—The spatial reference of the basemap
    • GCS_WGS_1984—A geographic spatial reference using degree decimals as units
    Note:

    Choosing GCS_WGS_1984 provides Longitude, Latitude, and Height options rather than X, Y, and Z options.

  11. In the From: Coordinates section, provide coordinate values for X, Y, and optionally, Z, for the from location.

    A green square is placed at the specified coordinate on the map for the from location.

    A green dot appears on the route at the location nearest to the green square. This is the location of the from measure value of the event.

    Tip:

    Click Choose measure from map Choose measure from map and click the location on the map.

    The route measure closest to the original coordinates is selected and its distance from the route is displayed.

  12. Specify the route in the To: Coordinates section by doing one of the following:
    • Click the Route Name drop-down arrow and choose the route.
    • Type the route name in the Route Name text box.
    • Click Choose route from map Choose route from map and click the route on the map.
  13. In the To: Coordinates section, provide coordinate values for X, Y, and optionally, Z, for the to location.

    A red square is placed at the specified coordinate on the map for the to location.

    A red dot appears at the measure on the route to which the coordinate values correspond. This is the location of the to measure value for the event.

    Tip:

    Click Choose measure from map Choose measure from map and click the location on the map.

    The route measure closest to the original coordinates is selected and its distance from the route is displayed.

  14. Optionally, specify the date that defines the end date of the events by doing one of the following:
    • Type the end date in the End Date text box.
    • Click Calendar Calendar and choose the end date.
    • Check the Route end date check box.

    The end date is optional. If no end date is provided, the event remains valid from the event start date and into the future.

    Add Line Event pane
  15. 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 are created. For additional information and examples, see the retire overlaps scenarios.
      Retire overlaps behavior simple scenario
    • Merge coincident events—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, the new event is merged with the existing event and the measure range is expanded accordingly. For additional information and examples, see the merge coincident events scenarios.
      Merge coincident events simple scenario
  16. Click Next.

    The attributes for the chosen event layer appear under Manage Attributes.

    Add Line Event pane with Manage Attributes
  17. Provide attribute information for the new event.
    Note:

  18. Click Run.

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

Add multiple line events by coordinates

Complete the following steps using the Add Multiple Line Events tool to create multiple line events using coordinates:

  1. Open the map in ArcGIS Pro and zoom to the location where you want to add the line events.
  2. On the Location Referencing tab, in the Events group, click Add > Multiple Line Events Add multiple line events.

    The Add Multiple Line Events pane appears with the default Route and Measure value.

  3. Click the From Method drop-down arrow and choose Coordinates.
  4. Click the To Method drop-down arrow and choose Coordinates.
    Add Multiple Line Events pane with Coordinates method
    Tip:

    You can use a combination of any of the methods to locate the from measure and to measure values. For example, you can use Route and Measure to choose the from measure value, and use Coordinates to define the to 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 chosen from method is Route and Measure and the chosen to method is Coordinates.

  5. Click Next.

    The Network drop-down list, and the From: Coordinates and To: Coordinates sections appear in the pane.

Referent offset when using the coordinates method

The Pipeline Referencing 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 values, geographic coordinates are used as the FromRefLocation and ToRefLocation values, and the FromRefOffset and ToRefOffset fields are populated with 0.

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 line event records that have referent values enabled.
