Motivation behind Contribution
“Volunteered Geographic Information
(VGI) is the harnessing of tools to create,
assemble, and disseminate geographic
data provided voluntarily by individuals.”
(Goodchild, 2007)

“These are just a few examples of a phenomenon that has taken the world of geographic
information by storm and has the potential to redefine the traditional roles of mapping agencies
and companies." – Goodchild
Examples include WikiMapia, OpenStreetMap, GISCorps, Gypsii, Google Earth, Cyclopath etc.
Problem Motivation
Motivation behind VGI….
• There’s a new road that we don’t have in GPS. “A new route” !
• Governments are reluctant to pay for increasing costs of mapping.
• Developing countries do not have digital street map.
• Disaster Management
Motivation behind contributors…
• Helps in designing VGI project in better and appealing way.
• Need for new volunteers and retain existing ones.
• Decreasing pool of volunteers [Independent Sector, 2001]
• Problems in volunteer’s retention to an organization [Bussel &
Forbes 2002].

“The open source Open Street Map (OSM) project plans to lend its support by
calling for volunteers to update its maps of Chile on the basis of the latest
satellite images. This will assist orientation and coordination of aid teams in
Chile.”
Problem Statement
Given
A set of VGI projects and spatial volunteers
Find
A ranked list of motivations factors behind volunteerism activity of volunteers
Objective
Better design of future VGI projects and improvement of existing VGI projects
by eradicating volunteer motivation issues or problems.
Constraints
To find a complete and correct list with proper ranking of motivational factors.
Proposed Solution
Methodology Applied
• Humans will be subject of research.
• Design of questionnaire.
• Review and revision of questionnaire
• Questionnaire will be presented as web survey.
• Collected results would be analyzed.
• Result analysis would lead to the ranked list of motivational factors and
comparison with already identified volunteer motivation factors.
Innovativeness
• Previous research [by Snyder & Clary]were done in 90’s. Till then there is
change in economy and availability of technology.
• The data is collected entirely from spatial volunteers.
• Goodchild has not mentioned any experimental approach to evaluate
reasons behind motivation.
