Adding point events by route and measure

Events on a route, such as crashes and traffic count sites, can be represented as single point events with measure information along the route. The Point Events tool allows you to create new point events.

1. Open Event Editor and, if prompted, sign in to Portal for ArcGIS or ArcGIS Online.
2. Click the Edit tab.
3. In the Edit Events group, click the Point Events button .

   The Add Point Events widget appears.

   If there are no editable point event layers, the widget is disabled.

4. Choose an event layer you want to edit from the Event Layer drop-down list.

   

5. Click the Network drop-down arrow and choose the network that will serve as a source LRM for defining the input measures for the new events.

   The Network is an LRS Network published as a layer in the Event Editor.

   You can specify the LRS Network to be used as the LRM for defining the measure of the new point event. The widget accepts an LRS Network as a source to identify the location for adding the new point event. However, when the new point event data is being stored in the database, the application performs an internal translation of measures to always store the measure value in the linear referencing method of the LRS Network with which the event is registered.

6. Type a route ID in the Route ID text box on which the new event measure will be based.

   Astuce:

   You can also click the Select a Route on the Map button to choose the route on the map.

   The selected route is highlighted on the map.

   

   Remarque :

   If a message appears that is related to acquiring locks, the need to reconcile, or not being able to acquire locks, Roads and Highways conflict prevention is enabled. For more information about these messages, see Conflict prevention in the Event Editor.

   Remarque :

   To create a point event on a redline, click the Select a Redline on the Map button . For more information, see Adding point events to a route redline.

7. In the Location section, type the measure value of the intended location for the new point event along the route in the Measure text box.

   Astuce:

   You can also click the Select From Measure on the Map button to choose the route location on the map.

   The new event will be associated with the route (route ID) from the LRS Network that the event location intersects. In cases where the input location intersection may have more than one route in the registered LRS Network (overlapping routes), a dialog box prompts you to choose which route you prefer the event to be associated with.

   A red cross symbol is dropped at the selected location on the map.

8. Click the Start Date and End Date calendar controls to choose the start and end dates of the event.

   The start date defaults to today's date, but you can select a different date using the date picker. The end date is optional.

   Remarque :

   If you configured your instance of Event Editor to not allow dates prior to the start date of the route and you enter a date prior to the start date of the selected route in Start Date, a warning message will appear alerting you to choose a date on/after the start date of the selected route.

9. Optionally uncheck the Prevent measures not on route check box if measures not on the route will be allowed.

   This data validation option ensures that your measure values fall within the minimum and maximum range of measure values on the selected route.

10. Click Next to view the Attribute-Value table.

    This table contains all the attributes of the event layer.

    

    Remarque :

    Coded value, range domains, and subtypes are supported when configured for any field in the Attribute-Value table.

11. Provide attribute information for the new event in the table.
12. Check the Show network name check box to see with which LRS Network the selected event layer is associated.
13. Click Save.

    The new point is created and displayed on the map.

After an event has been successfully created, you have the following two options to continue characterizing the route:

• When you click New Edit, all the input entries in the widget are cleared, and the default values from the geodatabase are populated in the attribute table.
• When you click Next Edit, all the existing entries in the widget and the attribute table are retained for the convenience of quick editing of similar characteristics.
