"Map" is both a noun and verb. Traditional notions of cartographic authority are challenged when maps drawn, revised, or overlaid with collective intelligence, subjective experience, or negotiated information. Although maps have been traditionally thought to provide definition to the real world, which is often contested, in today's media environment, it becomes more and more obvious that all maps make an argument. In a participatory culture, we both use (and critique) maps other people have made and make, collaborate, and share maps we have made. As new media facilitates broader participation in cartography, maps become a media requiring new media literacies.
