Self-explanatory or just easy-to-use? A theoretical approach to the emancipatory potential of volunteered geographic information (VGI)

Volunteered geographic information (VGI) has fundamentally changed the way in which geoinformation is generated, distributed and handled. It entails manifold practices and discourses which are currently investigated from both affirmative and critical perspectives. Expanding on the range of theoretical approaches to VGI, this article explores the condition and the limits of VGI from a social theory perspective to explore the following questions: what is the basic structure of VGI both as a form of practice and a form of knowledge? What are aspects of integration and aspects of divergence with regard to VGI practices? Are there inherent limitations to VGI practices especially with regard to its emancipatory and educational potential? To approach these issues several established analytical frameworks are discussed, and a specific categorization of VGFs symbolic geographies as interaction content will be introduced. Based on this categorization two opposed types of interaction practice can be distinguished: While information on VGI gathering and processing as a part of interaction content is vital to a competent use and deeper understanding of the system ("selfexplanatory") many interface designs have a very limited output in order to promote user-friendliness ("easy-to-use"). While the latter may increase the popularity of VGI it also limits interaction language to everyday language, to familiar spatial vocabularies of place, city, region, landscape or nation—instead of mediating technology's spatialities or exploring more innovative ways of spatial representation.
