Abstract

The goal of this second report is to review how social media are changing the way we collectively map the world. To reach this goal I review different collective mapping practices that characterize the social media era. First I examine the situation of community mapping in the context of new cartographic processes and technologies, with a focus on indigenous cartographies. I then review the use of volunteers in the production and representation of geospatial knowledge, with an emphasis on crisis mapping. Finally, I discuss how mapmaking in the social media era reflects major trends in terms of power relationships that occur between the state, its citizens, and the private sector. These trends reveal the replacement of the state as the main reference for the collection and dissemination of cartographic data, by a combination of private interest and individually volunteered contributions. Just as the specific interests of the nation state have largely helped to shape the reality produced by paper maps throughout the centuries, this new convergence of interests is now helping to shape the reality produced by digital maps through geosocial media.
