Examples

Use this widget to support app design requirements such as the following:

• You want to click a location on a route and get route attributes, measure values, and event attributes.
• You want to use route information to run additional queries and populate forms.

Usage notes

This widget requires connection to a Map widget. To identify routes and events, the Map widget must be connected to a web map data source published with an LRS with the Linear Referencing and Version Management capabilities enabled.

To create an LRS and publish a feature service with the Linear Referencing and Version Management capabilities enabled, follow the steps in the ArcGIS Pro documentation:

• Pipeline Referencing—Create an LRS and share an LRS as web layers
• Roads and Highways—Create an LRS and share an LRS as web layers

When you click a route on the map, the widget highlights identified routes and shows their attributes in the widget panel. The widget displays the measure value for the clicked point location and minimum and maximum measure values for the route.

If the point you click on the map intersects with more than one route, you can use the page navigation tools at the bottom of the Route Locations panel to review each route.

The widget can also display line event attributes and point event attributes.

Settings

The LRS Identify widget includes the following settings:

• Select a Map widget—Select a Map widget.
• Load Layers—Load layers from the web maps in the connected Map widget. To load layers, the Map widget must be connected to a web map with LRS layers.
• Clear Layers—Remove all loaded layers from the widget.
• Layer Configuration—Click a layer to open the Layer Configuration panel.
  • Label—Provide a meaningful label for the layer. This label appears in the widget panel at run time.
  • Use Field Alias—Turn on this setting to display field aliases at run time. An alias, or display name, is an alternative name for a field. It is usually a more user-friendly description of the content of the field. Unlike true field names, aliases do not have to adhere to the limitations of the database, so they can contain special characters such as spaces. This setting only appears for network layers.
  • Configure Fields—Choose which attribute fields from the layer to include in the widget panel at run time. This setting only appears for network layers.
• Default Network—If you add more than one network layer, you can set a default network layer.
• Selection Settings—Configure settings related to how the widget displays selected features.
  • Highlight—Use the color picker to choose a color for the selection highlight. The default color is cyan.
  • Width—Define the width for the selection highlight in pixels. The default width is 3 pixels.
• Show Line Events—Turn on this setting to display line events at run time.
  • Line Attribute Set—If a layer is configured with attribute sets for Pipeline Referencing or attribute sets for Roads and Highways, you can choose a default one from the drop-down menu. The widget only displays line events that are part of the attribute set. Attribute sets are collections of event layer attributes. You can use attribute sets to create multiple events with a set of additional, organization-specific attributes in a single edit.
• Show Point Events—Turn on this setting to display point events at run time.
  • Point Attribute Set—If a layer is configured with attribute sets for Pipeline Referencing or attribute sets for Roads and Highways, you can choose a default one from the drop-down menu. The widget only displays point events that are part of the attribute set. Attribute sets are collections of event layer attributes. You can use attribute sets to create multiple events with a set of additional, organization-specific attributes in a single edit.
