Diversity in volunteered geographic information: comparing OpenStreetMap and Wikimapia in Jerusalem

While the term “volunteered geographic information” (VGI) has become a buzzword in debates on the geoweb, online cartography and digital geoinformation, the scope and reach of VGI remains underexplored. Drawing on literature on social implications of VGI, this article, firstly, explores differences between VGI initiatives at the example of a comparative case study on social biases within data of OSM and Wikimapia in the fragmented social setting of Jerusalem, Israel. The results of this analysis turn out to be highly contradictive between both projects, which challenges widely accepted assumptions on the imprint of social inequalities and digital divides on VGI. This observation guides, secondly, a discussion of diversity within the category of VGI. Arguing that mapping communities, data formats and knowledge types behind VGI are extremely dissimilar, the paper proceeds by questioning the consistency and utility of VGI as a category. Seeking for a more comprehensive typology of VGI, Edney’s notion of cartographic modes will be presented as an approach towards a more contextualized understanding of VGI projects by embracing their underlying cultural, social and technical relations. Consequently, the paper suggests empirical research on the cartographic modes of a broad series of VGI projects through qualitative and quantitative methods alike. © 2016, Springer Science+Business Media Dordrecht.
