Study on VGI Volunteers
Rupa Tiwari, 12/02/2010
The harnessing of tools to create, assemble, and disseminate geographic data provided voluntarily by individuals (Goodchild, 2007). E.g. Wikimapia, Flickr, OpenStreetMap, Cyclopath
UMN east bank
Citizens as sensors: the world of volunteered geography by M.F. Goodchild, 2007
This geojournal summarizes few factors underlying VGI volunteerism, like:
“Self-promotion” (for non-anonymous projects only)
“convenient way of making it available to friends and relations” and
“Personal satisfaction” (for OpenStreetMap only).
It is unclear as how the motivational factors have been arrived upon. Probably the outcomes are influenced by volunteer communities of Citizen Science projects like Christmas Bird Count and Project Globe. There is no mention of any kind of experimental approach backing up the findings.
Major participants from USA, followed by Germany, UK & France
Ranked list table of the motivational factors:
Other factors as indicated my 5% of the survey participants were reasons like adventure,fun of working on new projects,fordemonstrating the benefits of spatial information technology during disaster situationsandimproving the use of geospatial techniques in local governments.
Relatively low Female participation with 37% in GISCorps and only 4% in OpenStreetMap
All age groups contribute, predominant being those between 20-50 years. OpenstreetMap seems to consist of younger lot of volunteers; the small fraction consisting of below 20 years of age is solely due to OpenStreetMap.
Majority of GISCorps volunteer’s professional work and areas of study are related to GIS. While for OpenStreetMap the opposite holds, they volunteer as a hobby.
Specifically speaking 46% of GISCorps volunteers volunteer on an annual basis whereas 46% of the OSM volunteers do so, on a weekly basis.
Around 69% of volunteers have been contributing for years or more.
55% of volunteers would undergo geospatial training only if it were free
