Display a route layer and its directions using a feature collection.
Use case
Routes can be stored as feature collection layers. These layers can store useful information such as directions, estimated trip time, and more.
You can create a route layer in ArcGIS Pro and store a route layer as a portal item, making it easy to access, share, or display.
How to use the sample
Pan and zoom to view the route displayed by the feature collection layer. Toggle to view or hide the turn-by-turn directions.
How it works
- Create a
PortalItem
with the default portal and item ID. - Create and load a
FeatureCollection
with the item. - After loading, get the
FeatureCollectionTable
containing turn-by-turn directions. - Set the
ItemSource
of the collection displaying directions to theFeatureCollectionTable
. - Create a
FeatureCollectionLayer
with the feature collection and set it to the map'sOperationalLayers
.
