Registering an X- and Y-coordinate offset event

In this type of reference offset event, an event layer is registered and posted with an offset against an X- and Y-coordinate location. The positive and negative offset values determine the direction of the offset relative to the X- and Y-coordinate location.

Attribute table for X- and Y-coordinate offset event

Pasos:

1. Start ArcMap and open the Catalog window or start ArcCatalog.
2. In the Catalog tree, connect to the geodatabase that contains the advanced linear referencing system (ALRS) and LRS Network for which you want to add event layers.
3. Expand the ALRS that contains the LRS Network for which you want to add event layers.
4. Right-click the LRS Network and click New > LRS Event.

   The ALRS Event Setup wizard appears.

5. Click Next.
6. Choose X and Y Coordinate Offset.

7. Click Next.

   

   The General Event Properties page of the wizard appears.

8. Type a name for your event layer in the Event Name text box.
9. Verify that the parent network is set to the correct network.
10. Click the browse button next to the Event Table text box.

    The Browse Data dialog box appears.

    Nota:

    For more information about setting up database connections to your external event database, see Registering an external event source.

    Nota:

    When adding local events to an SDE geodatabase, the event table must be registered as versioned.

11. Browse to the business table for which you want to create an event layer and click Select.
    If the table you browse to is in the same geodatabase as your LRS Network, you will create a local event. If the table you browse to is outside of the geodatabase, you will create an external event.

    The General event properties dialog box is populated with information from the event table.
12. Verify and update the rest of the information on the General event properties dialog box as needed.
    1. Set the Event ID Field that identifies the events.
    2. Set the Route ID Field that contains information about what route with which the event is associated.
    3. Set the From Date Field that stores the start date of the event being active.
    4. Set the To Date Field that stores the end date of the event after which it is retired.
    5. Set the Time zone for storing the date and time.
13. Click Next to set GPS Reference Offset properties.
    1. Set the X Coord Field that stores the X-coordinate of the location used for offsetting the event.
    2. Set the Y Coord Field that stores the Y-coordinate of the location used for offsetting the event.
    3. Set the Spatial Reference of the X- and Y- coordinates.
    4. Set the Offset Field that contains the values for offsetting the event.
    5. Set the Offset Units.
    6. Set the Snap Tolerance.
14. Click Finish to register a reference offset event from X and Y locations.
