Title: How Volunteered Geographic Information changes everything, and what it's worth?

Presentation Outline● 1. What is 'Volunteered Geographic

Information'?● 2. How VGI Impacts our lives● 3. Initial Study Proposal● 4. Recap/ Questions?

1. What is Volunteered Geographic Information

(why you should be getting excited)

1.1. Introducing VGI

● “The act of creating geographic information by largely untrained volunteers”. (Goodchild 2007)

● For this study, “data volunteered by the public for use with the public”

1.2. Introducing VGI Maps

● Taking 'Volunteered Geographic Information' and applying a geospatial element

● Example: OpenStreetMap

(OpenStreetMap 2009)

● “A web application that combines data from more than one source into a single integrated tool” (Wikipedia 2009)

● Gained widespread acceptance after introduction of Google Earth (Goodchild 2007)

1.3. Introducing Mashups

(Rolfe 2008)

1.4. Introducing Mashups● Mashups allow for

'emotions' to be derived from maps

– The Map as an interactive interface (Roush 2007)

– Shared experiences

● Photos● Videos● Photosynths

(Google Maps 2009)

1.5. Why Research VGI?● Very exciting field of

research● Vast future potential

in society– Landmark

navigation (May, Ross et al. 2003

● Potential to provide additional 'Value' to maps

1.6. Why Research VGI?

● A very important area of little research

● The 'Value' of VGI is undefined!

● The 'academic' field of VGI is yet to be fully 'defined'

2. How VGI Impacts our lives

2.1. Case Study

● The world is badly mapped (Goodchild 2007)

● What to do when aid relies on maps?

● How important is time?

(www.sodahead.com 2008)(Cak-cak 2009)

2.2. Case Study

● Create new maps in areas where no adequate map is available

– Gaza Strip 2009 (w ik i .o p e n s t r e e tm a p .o r g 2 0 0 9 )

● Mashup 'lost people' notices– Hurricane Katrina (Tapscott, Williams

2008)● Provide an emotive link to the disaster

– Experience Based Economy (Pine 2004)

3. PhD Study Proposal

3.1. PhD Study Proposal

● How VGI Map Stakeholders perceive 'Value'

● Human factors focus, not social psychology

● The first study to look into this topic

● Case study = OpenStreetMap

3.2. PhD Study Questions

1. Who are the stakeholders in VGI applications, and what are their relationships?

2. What is commonly perceived as 'value' in data amongst VGI Stakeholders?

3. How are electronic maps utilised in the online community?

4. Recap/ Questions?

4.1. Recap

● Researching what human factors influence the value of a VGI system?

● Mashups are the engines of social VGI● Little research in this important area● To be of use, one must understand Value● Value of VGI is currently undefined!● The 1st Case study will investigate

perceptions of 'value' in VGI Stakeholders
