Book excerpt: Media Boundaries and Conceptual Modelling forms part of the humanities tradition by facing one of the fundamental problems since antiquity: how different media represent the world we live in. It intersects also with the digital by addressing the problem with the help of a digital humanities method: computer assisted conceptual modelling. And it acknowledges the spatial turn by investigating the boundary between what has traditionally been the two main media for representation of geospatial information: texts and maps. It contributes to the further development of digital humanities and bridges the two areas of digital humanities and intermedia studies. Further, it strengthens the theoretical foundation for research and teaching in spatial digital humanities. The book meets the lack of critical discussion of the practice of digital mapping, offering a theoretically based understanding of such practices from a humanities perspective. More generally, it contributes to the theoretical discussion of modelling in digital humanities.
