(Currently) “missing” sensors....
Medium size sensor arrays (provincial networks)
What if we lower the barrier of publishing/finding/using sensor data?
Long Tail of Big Sensor Data(Liang, 2010)
Big IoT Data = SUM(small sensor data)
77% of the surveyed IoT experts claimed that Interoperability is the biggest challenge currently
facing the Internet of Things
(IoT Nexus, 2015)
Service Enablement, the real potential of Internet of Things (system of systems)
Network Effect: The value of a network is proportional to the square of the number of users of the system (n²).
Service Enablement transform user experiences

GeoCENS
GeoCENS • Funded by CANARIE, Cybera,
Microsoft Research, Agriculture and Agri-Food Canada
• An open sensor data portal (★ ★ ★ ★ ★) • Very easy to use • High performance
• A RBC Blue Water Project • affordable and scalable long
term groundwater monitoring • more than 40 well owners • data since 2008 • QA/QC by UofC Hydrologists

Project coordinator oversees all groundwater wells (QA/QC). She is the only person has the permission to edit and put notes for all wells.

CALGARY FLOOD 2013
Our data proven to be a high quality, near-real-time and complementary data source in addition to the official monitoring wells.
near 100,000 residents were evacuated from their home
The great thing about standards is that there are so many standards.
How smart is your city?
How fast can you move in the IoT (sensing) value chain?

Case Study #1• A pilot project funded by Department of Homeland Security and IJIS
Institute
• Problem:
• lacking a Common Operating Picture (COP) for various first responder groups and disaster managers
• Solution:
• SensorUp platform allows various group to access heterogeneous sensing systems

Conclusion• Service Enablement
• Location always matters!
• Big IoT data = SUM(small sensor data)
• How smart is your city? Depends on how fast can you move in the IoT value chain.
• Stop building silos!
