Volunteered Geographic Information for Qualitative
Spatial Research with a focus on Health and Place
A Dissertation Proposal
Bill Buckingham
• How do we constructively capture, consume, visualize and analyze location based qualitative data? – Can it result in something useful? – How so? – Is it extensible? Can it be specific (e.g. health)?– Can it contribute to mixed-methods research?
Why does this research matter?
• Existing Geovisual applications are poorly equipped to support place based qualitative data
• No framework currently in place to handle qualitative spatial data
• Develops methods to interface with hard to reach populations
• Within native environment• In their own words
• Near real time surveillance• Allows dissenting voices to be captured• The system stays in the community after the research is
completed.
PPGIS & VGI
• Access Data• Neg: Political• Process & Outcomes
• Create Data• Neg: Frivolous• Applications &
InformationDifferences are not always clear!
Definite Overlap, but not clear how much!
Why VGI?
• Less GIS – More Location• Not Explicitly Group Based – Individual• New voice for the local (Goodchild 07)• New avenue for PH surveillance• Encapsulates Social Media
VGI Issues
• Access!• Credibility• Privacy
