Agenda
Lightning Project Overview Real-Time Sensors FME Processing Products
Lightning
Lightning is Dangerous Deaths = estimated 9-10 per year Injury = estimated 164 per year Costs to businesses, infrastructure and insurance “Bolts from the Blue”
Frequency lightning flashes occur in Canada about 2.34 million times a
year, including about once every three seconds during the summer months.
We benchmark tested 50,000 strikes a second (aka stormagedon)
Project Goals
Public Alerts through: Alerts on TWN’s Website Alerts on local TV segments Alerts via Text/SMS and Email Alerts via Mobile applications
Also: Dynamic maps Interactive tools (distance calculator)
“To provide information for the public’s safety and wellbeing”
What type of Sensors do you use?
AVL Snow removal equipment Fleet tracking (emergency vehicles, taxis, bus
routing etc…) Vessel tracking (e.g. exact earth)
Smart grid Refrigerator? Smart cars (e.g. tesla) Mobile phones, Twitter, Instagram, social media
Real-Time Sensors
Pelmorex Lightning Detection Network
Project Infrastructure
