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. The volume of data collected to record monuments and landscapes may now be vast, and levels of accuracy and precision unprecedented. This growth in data quality and volume has to some extent been accompanied by a reluctant theoretical debate, largely about method and meaning in the practice of survey. Less well explored is the area of visualisation of survey results, which 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. This paper explores the potential of computer game software to produce accurate, immersive and interactive visualisations of digital survey data of archaeological monuments.

  • 1. Lasers, Landscape and Muddy Boots Potential Applications for Immersive Visualisation of Airborne Lidar Keith Challis Institute of Archaeology & Antiquity University of Birmingham U B
  • 2. Lasers, Landscape and Muddy Boots
    • "The real work (in the study of landscape) is accomplished by the men and women with muddy boots..." W.G. Hoskins.
    Keith Challis University of Birmingham
  • 3. Lasers, Landscape and Muddy Boots
    • The volume of data collected to record monuments and landscapes may now be vast, and levels of accuracy and precision unprecedented
    • Conventional visualisation of TLS/ALS and survey data, has tended to remain rooted in traditional approaches, albeit facilitated by new digital media
    • Modern digital survey can engage with others areas of archaeological debate such as discussions of sense of place, meaning and interpretation in landscape, as embodied by for example the phenomenological approach to landscape

    • Another Perspective: Thirdspace
    • Thirdspace - spaces that are both real and imagined 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.”
    Keith Challis University of Birmingham
