Real-Time GIS
Real-Time GISIntegration and exploitation of streaming data
• Integrates real-time streaming data into ArcGIS
• Performs continuous processing and real-time analytics
• Sends updates and alerts to those who need it where they need it

Stream Services
Getting Real-Time data into Web Apps
• Feature layers pull from feature services- Web apps poll to get periodic updates- Must be backed by an enterprise geodatabase (EGDB)
• Stream layers subscribe to stream services - Web apps subscribe to immediately receive data- Low latency and high throughput
Send Features to a Stream Service
• Are discoverable via services directory- http://<your server>/arcgis/rest/services/iss-stream/StreamServer
• Can be secured just like any other ArcGIS Server service using- ArcGIS internal user store- Active Directory/LDAP- PKI
• Can be scaled using clustering
The foundation for real-time web appsStream Services
Stream Service
Real-Time in the Server
Demo
Enabling real-time web appsStream Layers
• Part of the ArcGIS API for JavaScript• Subscribe to stream services
- Immediately receive and render data- Configurable symbology with familiar api- Direct access to data on arrival
• Can filter on- an area of interest- field values
• Stream services communicate over a web socket- Web socket protocol must be allowed on network- Client must have a browser that supports web sockets

Enabling real-time web appsStream Layer Deployment Patterns
• Configure in a Web Map and - Just share it - Web App Template- Web App Builder
• Custom JavaScript apps

Summary
• Stream Services - enable low-latency immediate delivery of data- are discoverable, securable and scalable
• Stream Layers- Consume and Display streams of features- Configurable symbology - Filter by Geometry and Attribute
