Media rich geographical environments and mobile Geomedia are suspected to change the way we encounter cartographic material. Thereby, commercial geomedia such as Google Earth promise to work as devices that not only facilitate the access to geographical material, but provide interactive platforms that makes it easier to handle and comprehend spatial relationships, and, at the same time, reconfigure our understanding of space and location. The paper argues that these developments demand an overall shift from the fixed functional approach of map use studies to a more dynamic view on geomedia usage that becomes inevitable through new practices such as geobrowsing. This claim is reviewed, drawing on Science and Technology Studies, and, in particular their research branch Actor-Network-Theory, to give further insights in the handling of geomedia, against the backdrop of the socio-technical context in which the objects influence our everyday encounters with the outside world.
