The Projection Augmented Relief Model (PARM) technique is presented, which aims to combine the affordances of digital mapping and physical landscape models. The technique is designed to provide an engaging and informative situated display, offering an intuitive frame of reference for placing objects, activities or events into their spatial context. It also has potential to act as an integrative framework through which visitors might learn about connections between themes being displayed elsewhere in the gallery space. We describe our experiences of creating and displaying a prototype model and the specific context in which it is being deployed. We also offer a research agenda for further exploration of this technique, including ongoing work to define the measurable benefits in relation to spatial knowledge acquisition.
