Lightning!
! …is Dangerous ! 9-10 deaths, 164 injuries per year ! 4,000 forest fires ! 500-600 power outages (Manitoba)
! …is Frequent ! 2.34 million strikes per year (1.4 billion worldwide) ! 1 strike every three seconds during summer

Events, Alerts, and GIS
Event
Geo-fence
Notification
Action
Geo-fence Virtual Perimeter or Area of Interest
Spatial Predicates Relationships
Am I affected by the event (overlap)? Will I be (route intersection)?
Am I close to an event? Where is the nearest event?
Real-Time Processing

Setup ! Listen for a lightning strike (open TCP/IP port) ! Write to PostGIS ! Spatial Processing ! Other logic ! Generate customized JSON message ! Dispatch message via JMS Key Transformers
! TCPIPReceiver ! PointOnAreaOverlayer ! Tester ! JSONTemplater ! JMSSender

Implementation
Challenges ! High volumes of Real-time data ! Cross-platform development ! Short time frame (six months)
We benchmark tested
strikes a second (aka Stormageddon)
50,000
