Background 2.0
“Central control of computer databases, such as GIS, tend to increase the power to the bureaucrats, administrators, technical experts and computer
literate groups who use them at the expense of those who lack the expertise to access to these systems”
Arnoff (1989)
“Naïve geography is a necessary underpinning for the design of GISs that can be used without major training by new user communities
such as average citizens, to solve day-to-day tasks”
Egenhofer and Mark (1995)
“Instead of asking how to find the need or data people want, instead ask how to allow the public needs to inform and drive data collection and access”
Huang and Chuang (2005)

Background 3.0
“Neogeography is about people using and creating their own maps, on their own terms and by combining elements of an existing toolset. Neogeography is
about sharing location information with friends and visitors, helping shape context, and conveying understanding through knowledge of place”
Turner (2006)
“This new phase of development is the wikification of GIS, which is driven by the massive and voluntary contribution among both amateur and experts using
Web 2.0 technology”
Sui (2008)
“Another source of interest in GIS becoming a tool of participatory democracy has been the need to reinvingorate traditional models of citizen involvement in
making decisions about the use of public , natural resources”
Jankowski (2009)
