Gissen interprets architecture’s contemporary use of mapping, fieldwork and data as the renewal of a long disciplinary relation with geography. His iconic argument is that datascaping and research architecture are not signs of a post-theoretical realism but performative extensions of historical engagements with cosmography, territory and the production of terrestrial difference. The theoretical contribution lies in displacing geography from background description to an active architectural method. Maps, demographic distributions, border studies and environmental datasets do not merely represent sites; they construct new objects and positions for design. Methodologically, Gissen moves genealogically from early Vitruvian texts and state surveys to contemporary territorial research, revealing continuities beneath apparently novel techniques. The conceptual operation is geographic actualisation: architecture reorganises its disciplinary limits by adopting instruments that make political, economic and ecological relations spatially operative. The wider bridge reaches critical cartography, landscape theory, urban research and STS. Geographic methods thus become both analytical resources and contested devices through which difference is measured, visualised and governed.
