At CAA I was able to record some of the keynote talks. Here they are:

Towards a new landscape archaeology?

There can be no doubt that advances in the methods for archaeological remote sensing in the last few years have revolutionized what we can see of past landscapes. Technology now allows us to see buried landscapes more clearly, with greater resolution and over larger areas than had hitherto seemed conceivable. Furthermore, the complementary use of different techniques for survey and the improvement in computer software has generated excellent results both at individual sites and increasingly across broader landscape. We can and do learn more and more, but this raises a doubt in my mind, triggered by a discussion at a conference a couple of years ago about ‘ground truthing’. Have our technologies moved beyond the intellectual framework within which we are working? And do we not need to start to re-think the whole idea of landscape archaeology in the light of the new technology. This paper will explore this question, even if it cannot provide an answer.

The Use of 3D Models for Intra-Site Investigation in Archaeology

In the last few decades, the development of technology to aid in documenting, analysing and communicating information regarding archaeological sites has strongly affected the way scholars and researchers use and perceive the archaeological information retrieved during the field investigation process. Currently digital instruments are used in archaeology at every level and their employment during field activities increases the possibilities to document and visualize, with high accuracy of details, information detected in the field. In the frame of excavation practice, the development of powerful visualisation platforms, such as the Geographic Information System (GIS), and the introduction of digital acquisition tools, have provided archaeologists with the opportunity to fully reconstruct and study the spatial and temporal relations between the different strata detected on site in three dimensions (3D). This innovative new approach allows defining new field documentation strategies, through which it is possible to achieve a more accurate and detailed overview of the investigation process and to perform different new typologies of analysis in support of the site interpretation.

Computer Graphics Techniques for Analysis

For the past two decades there has been extensive work using computer graphics in cultural heritage. The field of computer graphics offers powerful techniques for communication and documentation. Public communication is still the major use of computer graphics, with still images, movies and interactive displays being used to render views of the past to modern audiences. In the area of documentation, computer graphics researchers have contributed to the development of 3D scanning techniques and novel imaging approaches such as reflectance transformation imaging. In the course of pursing these applications however, researchers have found that computer graphics techniques can be used for analysis as well. Several types of analysis will be presented including understanding material properties and shape to inform physical conservation, understanding how artifacts were manufactured, and understanding how artifacts were meant to be viewed and used. Examples will be drawn from the speakers projects at IBM and at Yale, as well as from other computer graphics projects from around the world. Open challenges such as organizing massive visual collections associated with an archaeological site will be described.
