I'm in the process of writing a presentation on the potential applications for immersive visualisation of airborne lidar for the upcoming symposium on Technological Advances in Landscape and Heritage Management Recording to be held at University College Dublin on 12th August.
Among a plethora of papers on technical aspects of airborne and terrestrial laser scanning I'm trying to get across a point about the deficiencies of conventional visualization of high density landscape data. Methods of survey have developed dramatically in the recent past with the advent of new digital survey techniques, global positioning airborne and terrestrial laser scanning and the volume of data collected to record monuments and landscapes may now be vast Growth in data quality and volume has been accompanied by a reluctant theoretical debate, largely about method and meaning in the practice of survey. The visualisation of survey results has tended to remain rooted in traditional approaches, albeit facilitated by new digital media. The ability of modern digital survey to engage with others areas of archaeological debate, for example discussions of sense of place, meaning and interpretation in landscape, as embodied by for example the phenomenological approach to landscape has largely been ignored as it is poorly addressed using conventional static visualisation techniques.
So game software offers the potential to engage with data not just through a cognitive analytical process, but experientially, by inhabiting a virtual rendition of the surveyed landscape. And once rendered this hyperreal landscape can be populated with all manner of data, from surveyed facets of monument and landscaape morphology, to the vestiges of historical documentation and the impressions of viewers. What comes to mind is the concept of thirdspace, coined by urban geographer Edward Soja -
“everything comes together… subjectivity and objectivity, the abstract and the concrete, the real and the imagined, the knowable and the unimaginable, the repetitive and the differential, structure and agency, mind and body, consciousness and the unconscious, the disciplined and the transdisciplinary, everyday life and unending history.”
But that might be going a little too far for the present...
