The Macroscope Vision
• The unprecedented amount of sensors will allow us to
• observe the world at very high spatial resolution
• perform these observations continuously
• collect them in digital form
• They will all be connected to the Internet

• Sensor/Data are scientists’ precious...
• They hide their precious...
• They don’t share their precious...
• But...their precious might be able to help others to save the world....
• And...even if they want to share and collaborate, there is no easy way...
Links between sensors are missing....

Crowd may not the solution for every
problems...

But for some problems, crowd might be the best solution.

Crowd Characteristics
• Time Critical
• Rich Context
• Unlimited Growth
• Pareto Distribution
• Long Tail
Sensor Web Long Tail

Crowd can do great work, if we can provide
them...

2. Search engine
• make it possible to find available data
3. Standards
• make it possible to access
4. Collaboration platform
• social networking
• able to upload/edit
