Integrating Human Observations and Sensor Observations – the Example of a Noise Mapping Community

Integrating Human Observations and Sensor Observations – the Example of a Noise Mapping Community Theodor Foerster Institute for Geoinformatics (ifgi) Workshop DE2010 20th September 2010

Do you hear it?

Threat
Hearing loss
Cardiological effects
Stress
Annoyance

Different emitters
Traffic
Airport
Industries
Everywhere!

Example
Example - no fake
SFO airport
source: stern.de

SFO map Source: tx-sfo.airportnetwork.com

Legal motivation source: European Commission

Interest in noise Noise vs. climate change Noise vs. global warming

How to share and create noise data
Using sensors
VGI!
Publish data centrally
Spatio-temporal analysis

Example project source: http://www.mappingforchange.org.uk

Noise mapping - currently
Not digital
No full coverage
Only local at a specific time
Integration missing
 Use case driven & expensive

Idea
Noise mapping community
Constantly measure noise through smart phones
Global scale
Android app
Build the Human Sensor Web
Existing Sensor Webs (from authorities)
Example: Flightwise.com
Human observations

Designated sensors source: ibm.com Human sensor observation

Architecture

Open issues
Power consumption
Sampling rate
Human observations
Trust & Accuracy
Semantics
Validation
How to build a community?
Incentives & motivation

Conclusion
Human Sensor Web
Applicable to other VGI scenarios
Project at the start
Still open questions

Thanks for your attention!
