Streaming feature layers created from an ArcGIS Server stream service provide data updates as they occur. They are useful for visualizing real-time data feeds that have high volumes of data or that have data that changes at unknown intervals. For example, a fleet of vehicles might be transmitting their location, and the current location of the vehicles needs to be continuously monitored.
When you add a streaming feature layer to Map Viewer, you can control the data sent from the service to the layer.
Follow these steps to control streaming features in Map Viewer:
- In the Contents pane of Map Viewer, click Options
on the streaming feature layer. - To control whether data is streamed to the layer in the map, click Show streaming controls and choose one of the following options:
- Stop—When you stop streaming, the data in the layer stops updating in Map Viewer and the data in the layer does not update until you start streaming again.
- Play—Use this control to start streaming data again.
- Clear—Use the Clear option to remove the features of a stopped streaming feature layer from the map. When you start streaming again (in other words, when you click the Play option), the layer will draw again.
Tip:
As with all feature layers, you can apply an attribute filter to the streaming feature layer to limit the data in the map based on attribute values.
