Matthieu Noucher is a geographer and researcher at CNRS, in the Passages laboratory of Bordeaux. His research focuses on the evolution of the representations of space through the analysis of new ways of producing, using and disseminating digital geographic information. He is particularly interested in the political and social dimensions of changes of the geographical representation of the world, related to the development of uses of geolocation technologies and the intrusion of non-specialists into cartographic production (citizen science projects, participatory or collaborative mapping, counter-mapping, etc.).
