This thesis introduces and analyses a unique approach which involved iteratively engaging with stakeholders to generate a film about sea-level rise at a heritage site. The project used fine-scale remote sensing techniques, including airborne and terrestrial laser scanning (TLS), to produce spatially accurate and realistic 3D digital visualisations of projected sea level rise at Cotehele Quay, a site on the River Tamar in Cornwall which is owned and managed by the National Trust. Area residents and stakeholders were involved in a series of focus groups which provided guidance on the integration of the spatial models into a short film. This thesis makes an original contribution to knowledge about how non-scientific audiences understand and interpret visual realism and spatial accuracy when engaged with the process of developing such a tool. Ultimately, the thesis proposes a new kind of visual realism based on this knowledge, known as ‘participatory realism’. The main output of this research was a film, ‘Changing Tides at Cotehele Quay’, which is presently being used by the National Trust as part of their wider communication toolkit. In addition to reflecting on the production of the film, the thesis makes the argument that at present TLS is not being proactively used to engage wider audiences. The research explored how TLS and other spatial data can be used in settings which are more public-facing; the thesis analyses the results of this innovative practice and interrogates the way in which people interacted and responded in the course of their participation.
