  • Next slide – who I am and what I DO
  • Research potential impact of volunteered data that professional data can not provideIdeas in Transit + Loughborough UniversityResearch how VGI and traditional Cartography can be combined together to produce new forms of map based productsNot in the computer science sense of ‘can we do it’ but in the human factors sense of creating products of higher worth and ‘enjoyment’ to consumers than either VGI or professional information alone.In the last year I have been out researching this with various groups and attending conferences such as State of the Map 2009 and 1st Geograph conference.
  • How volunteered information can be used with professional information to produce products and services of higher user value than either VGI or PGI aloneThese are the gaps in known literature I will address
  • Quick recap of what VGI isthe problems with naming phenomenon in the literatureMy address of the situation
  • General overview of Neogeography and VGI
  • Some of the 14 names used to describe the Neogeography Phenomenon
  • NEOGEOGRAPHY IS THE ENTIRE THINGVGI is similar to PGI (OSM being open source Ordnance Survey)Within potential scope of traditional cartographyVGLI is something different from both – can only come from communityOutside of traditional cartographyVGLI – birdwatchers
  • Overlap between PGI (Ordnance Survey), VGI (OpenStreetMap) and VGLI (Rotten Neighbours)
  • Lots of work in:Santa Barbara (USA)UCL (UK)Bonn (Germany)Etc.
  • Clear up two terms which are different but complimentary
  • Aims of the research – starting out almost blank in October 2008At the start of this study, the position of human factors within VGI, and associated elements of User-centred Design may be considered unknown.Distinct lack of human factors research into VGI (Harding, Sharples et al. 2009)
  • We have seen these Research Questions beforeFocus on VGI in the strictest state, OpenStreetMapNext slide go over methods used in addressing these two issues
  • Rich Picture – Monk & Howard
  • LAST SLIDE ON THE FINDINGS – summary next
  • Tackle the other research questions
  • Research Aims#1 most important in shaping studyDirects us towards focusing on VGLI rather than VGI
  • Where to start – finding a communityPoints – what will make a good communityComing up – rich picture then Andy’s drawing
  • Click for the shapes to appear
  • difficulty of courses, parking spots, landing points and local amenities. Information on course may depend on water levels which may change rapidly over a 24 hour period.Their results should be transferable to other groups who use ‘dynamic data’NEXT SLIDE – REMINDER OF CONDITIONS REQUIRED
  • Highlight how Kayakers fit the requirements
  • Diagram to show
  • 4 main points
  • Today’s slides are already online on the blogDiscussion points- What do you think of VGLI
  • Understanding the Volunteer in VGI

    14. 14. 2 Why Research Human Factors?<br />14<br />
    15. 15. 2 Why Research Human Factors<br />To date little research in this area<br />Focusing on human issues may allow for higher ‘value’<br />Net benefits over net sacrifices (Zeithaml 1988)<br />Need to address the issues of usability of VGI products<br />Useful, usable, satisfying to use<br />15<br />
    16. 16. 2 Why Research Human Factors<br />Usability <br />A set of attributes that bear on the effort needed for use, and on the individual assessment of such use, by a stated or implied set of users (ISO 9126)<br />Human Factors<br />A philosophy based on the needs and interests of the user, with an emphasis on making products usable and understandable (Norman 2002)<br />16<br />

    21. 21. 21<br />3 Current Research<br />
    22. 22. 22<br />3 Current Research<br />Consumers select their map product to best fit their circumstances with little loyalty to the brand: <br />Apart from using it like everybody does in terms of looking for places and directions, I’ve used Google My Maps, at the moment mainly for my own use... I’ve used it in a work context because I was trying to organise a meeting.<br />
    23. 23. 23<br />3 Current Research<br />Special Interest Mapping Groups (SIMGs), contributors (SIMGCs) and professionals are particularly vested in the use of their groups’ map:<br />I’ll often check out to see if the local CTC has a website [same map project involved in] to see what’s on there. And being able to find where the tea places are in the locality is quite useful.<br />
    24. 24. 24<br />3 Current Research<br />SIMGCs produce data for group members and external parties to use their data:<br />It’s mainly just a project to collect data... we hope other people will use it for whatever they feel free to use it for.<br />
    25. 25. 25<br />3 Current Research<br />SIMGCs are less concerned about inaccuracies as they have a vested interest in improving the data - seeing gaps as opportunities:<br />It has its faults but there are no glaring errors... It’s very much if you don’t like it you can fix it yourself which appeals to my, well, sense of working I suppose.<br />
    26. 26. 26<br />3 Current Research<br />SIMGs and professionals can be in constant tension with each other as their agendas and ideologies do not necessarily fit with each other. <br />It kind of annoys me that Google are potentially using the same kind of idea. [OpenStreetMap SIMGC]<br />
    27. 27. 27<br />3 Current Research<br />Between professional bodies, business rivalry may exist but they work alongside each other. <br />I will be chatting to my opposite number at Microsoft, and my opposite number at Google... we shouldn't even be friendly for Christ's sake according to the old fashioned rules of how you do business, and those old fashioned rules don't really apply any more.<br />
    28. 28. 3 Current Research<br />The main stakeholder groups are identified<br />Consumers, <br />Special Interest Mapping Groups<br />Local Communities <br />Professionals<br />The Rich Picture effectively provided context to the research outcomes and represented stakeholder relationships in an easily accessible fashion. <br />Different stakeholders will perceive elements of VGI very differently, based on which stakeholder group they may be identified with.<br />If considering value as the improvement to a stakeholder’s condition through utilising VGI, a salient increase in stakeholder value can be observed in all functional and work related perceptions<br />The implication of this work should be to provide a framework of VGI stakeholders to be utilised within future user-centred VGI research <br />28<br />28<br />
