What is Real-Time GIS?1
GIS DataWhat has happened, what is happening, what will happen

SpatiotemporalBig Data Store
Map and Feature Service
• Ingest high velocity real-time data into ArcGIS
• Perform continuous analytics on events as they are received
• Store observations in a Spatiotemporal Big Data Store
• Visualize high velocity and volume data:
- as an aggregation- as discrete features
• Notify those who need to know about patterns of interest in real-time

Working with Real-TimeData2
Working with Real-Time DataMaking features come alive• Connect an output to your feature/stream service• Import the schema of your feature as a GeoEvent Definition• Configure an input to receive real-time data• Author and publish a GeoEvent Service• Visualize your real-time features

Applying Real-TimeAnalytics3
Applying Real-Time AnalyticsGeoEvent Services• A GeoEvent Service defines the flow of GeoEvents
- The Filtering and Processing steps to perform- what input(s) to apply them to- and what output(s) to send the results to
Applying Real-Time AnalyticsGeoEvent filtering• A Filter eliminates GeoEvents based on an expression

• You can perform continuous analytics on events as they are received using a processor.

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

Wrap-up5
SummaryReal-Time GIS: GeoEvent Extension
• ArcGIS is a dynamic system that enables continuous analytics and real-time visualization for better understanding of our world.
• The Real-Time GIS capabilities allow you to:- know what is happening, as it happens- react and make smarter decisions faster- be notified when events of interest occur
