The Select a Redline on the Map functionality allows roadway characteristic editors the ability to add events to redlines. It provides them the ability to characterize the roadway with the appropriate attributes before the LRS editor has added or fixed the route in the LRS so their workflow is not impeded by having an incorrect LRS route based on current information. For more information on redlines, see Redlining a route.
- This functionality is only available when you have included the redline layer in the map service configured against Event Editor. For more information on how to deploy redlines in Event Editor, see Deploying redline routes.
- The tool works for redlines with Create Route or Reverse Route activity types.
- For the reverse route redline, the measure provided upon storage will be translated to the measures required to position the events at the same location before the reverse.
You can use the following steps to add linear events using redlines. A redline with the following attributes is used for this example.
- Open Event Editor and, if prompted, sign in to Portal for ArcGIS or ArcGIS Online.
- Click the Edit tab.
- 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.
- Choose an event layer you want to edit from the Event Layer drop-down list.
- Click the Network (LRM) 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 (LRM) 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.
- Click the Select a Redline on the Map button to select the redline from the map.
You can also click the Route ID drop-down arrow and click Choose Redline, then type the route ID for which the new event measures will be provided.
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.
The redline will be highlighted on the map.
- Enter a measure of the intended location for the new point event along the route using any one of the following methods:
- Type the values in the Measure text box.
- Click the Select From Measure on the Map button to choose a route measure on the map.
- Choose the Use the Route Start or Use the Route End option using the drop-down arrow from the Measure option.
The values will be populated with the geometric length of the redline. A red cross symbol is dropped at the selected location on the map.
- Choose the date that will define the start date of the events by doing one of the following:
- Click the Start Date drop-down arrow to choose the start date using a calendar.
- Check the Use route start date check box to use the start date of the routes.
The start date defaults to today's date, but you can choose a different date using the date picker. The end date is optional, and if it's not provided, the event remains valid now and into the future.
- Choose the date that will define the end date of the events by doing one of the following:
- Click the End Date drop-down arrow to choose the end date using a calendar.
- Check the Use route end date check box to use the end date of the routes.
- Click Next to view the Attribute-Value table.
This table contains all the attributes of the event layer.
Coded value, range domains, and subtypes are supported when configured for any field in the Attribute-Value table.
- Provide attribute information for the new event in the table.
- Check the Show network name check box to see with which LRS Network the selected event layer is associated.
- Click Save.
The new point event is now created on the redline 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.
