Geomedia is an emerging concept that has been deployed to capture a particular technological condition, associated with recent rapid developments in digital technology. As such, it signals to the dialectics of locative media and the mediations of localities. However, the concept of geomedia carries deeper/wider ontological and epistemological registers that transcend the simple twining of geography and media. In this wider sense, geomedia gestures to the expanding interdisciplinary terrain at the crossroads of media studies and geography, where various ontologies and epistemologies of space/time, flows/mobilities and mediation/ mediatization come together. The aim of this special issue is to explore the urban as a key terrain where these ontologies and epistemologies are articulated.
