The 2012 conference in rapidly approaching and next year, unlike the past few years, it is being held close to home, for me at least; hosted by the Archaeological Computing Research Group at the University of Southampton.
Geoff Avern and I are running a session looking at 3D archaeology and since the call for papers has been extended, there is still time to get a paper in should you wish to via the online submissions system.
The abstract for this session is as follows:
Over the last decade, new digital spatial technologies have become widely available for the capture, processing, analysis and visualisation of 3D data. Often originating in other disciplines, these technologies have been adopted by archaeologists for a range of purposes, with some groundbreaking results.
Terrestrial Laser Scanning (TLS) is now routinely deployed to record archaeological sites, monuments, earthworks, buildings and other structures. Close Range Laser Scanning (CRLS) is used to record artefacts and structures. Airborne Laser Scanning (ALS) is used to record large areas of countryside and even see through tree cover. English Heritage have now produced guidance on the use of TLS and ALS in archaeology, demonstrating that these are now established technologies within the heritage sector. Metrology systems are also being used to record features and fine surface detail at a range of scales whilst novel approaches using photographic techniques are being used to produce Digital Surface Models (DSMs) at scales from microns to tens of metres, suitable for use with individual artefacts through to entire landscapes. Photographic techniques alone or combined with TLS are also being used to produce 3D models in some cases equivalent to photogrammetric output but without the for complex site photography arrangements.
Combined with these data capture technologies, visualisation and analysis techniques such as Polynomial Texture Mapping (PTM) or Reflectance Transformation Imaging (RTI) are being used to visualise and investigate real-world objects and structures in addition to virtual objects, structures and landscapes at any scale. Laser scanning software now facilitates working with massive point clouds from TLS, CRLS, ALS or even submarine bathymetric datasets and provides means of integrating colour and photographic information. Automated or semi-automated vector extraction allows models to be created from these rich datasets for use in traditional workflows or integrated with Google Earth, CAD, 3D modelling packages or GIS. Orthographic views of 3D datasets, particularly those with colour data present, allow for the rapid creation of scaled, almost photographic like images which can be used in conjunction with or in place of traditional drawn plans and elevations. GIS, whilst being inherently two-dimensional, is being used in novel ways to analyse and interpret ALS data.
This session aims to showcase innovative and exemplary, current and emerging digital spatial technologies and applications of them in heritage contexts. With numerous potential approaches to recording, visualisation and analysis, bringing together the various techniques to be compared and contrasted will promote cross-fertilisation of ideas through qualitative assessment; critical appraisal of the technologies and their current and potential applications is an essential part of this and it is anticipated that through active discussion and sharing of experiences, best practice regarding such applications can be promoted and further developed.
Papers should focus on one or more of the following subject areas:
- Photographic and photogrammetric data capture technologies
- High resolution (sub-millimetre) data capture technologies
- Mid-resolution (millimetric-centimetric) data capture technologies
- Large scale (metric and above) data capture technologies
- Process, workflow and data integration
- Analytical techniques and methodologies
- Visualisation techniques and methodologies
