We aim to investigate and develop methods and technologies to transfer extensive repositories of historical media and their contextual information into a three-dimensional spatial model, with an additional temporal component. This will make content accessible to different target groups, researchers and the public, via a 4D browser. A location-dependent virtual reality representation can be used as an information base, research tool, and to communicate historical knowledge. The data resources available for this research include extensive holdings of historical photographs of Dresden, which have documented the city over the decades, and digitized map collections on the Deutsche Fotothek (German photographic collection) platform. These will lay the foundation for a prototype model which will give users a virtual experience of historic parts of Dresden.
