  5. 5. 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
  6. 6. Vineyard Computing Burrell, J., Brooke, T. & Beckwith, R. Vineyard computing: sensor networks in agricultural production. Pervasive Computing, IEEE 3, 38-45 (2004). !
  7. 7. Links between sensors are missing.... • 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... – Dr. Steve Liang – http://sensorweb.geomatics.ucalgary.ca –
  8. 8. Unleash the Power of Sensors Innovation in Assembly A Web of Sensors – Dr. Steve Liang – http://sensorweb.geomatics.ucalgary.ca –
