GIM International, September 2012 cover featuring Archaeological Survey at Sandsfoot Castle
The latest issue of GIM International contains a feature article on one of the projects I managed for Wessex Archaeology. The article talks about some of the tools, techniques and technologies used on this and other archaeological survey projects these days.
Archaeologists nowadays have a broad range of geomatics tools and techniques available to help them in their work. Whilst measuring tapes and dumpy levels are still essential instruments found on archaeological sites across the world, many projects now include Terrestrial Laser Scanning (TLS), Global Navigation Satellite Systems (GNSS), robotic Total Station Theodolites (TST) and a variety of photographic and photogrammetric methods. Spatial data is then handled in 2D and 3D using CAD and GIS. These modern tools allow archaeologists to record our heritage with greater precision and faster than ever before whilst producing rich spatial data for visualisation and analysis.

This year, as part of the Festival of British Archaeology, I am very lucky to be managing a dream geomatics project which has a load of associated special events for the Festival. As a frustrated pilot and a well known geek, I love my gadgets, particularly those which fly. Well, this year, all my Christmas’s have come at once. Continue reading →
I’ve been meaning to have a proper go with Storify for a while now and so have taken the opportunity to document a recent talk I gave and some follow up discussions. As usual, presentation itself is on Slideshare. Continue reading →
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. Continue reading →
Key weapons in the armoury of the 21st century archaeogeomancer include some rather magical satellite and laser based devices, which I often talk about. These fantastic devices allow archaeologists to take GIS data out into the field and record new data all with minute precision. Archaeologists have long used survey techniques and these are just the latest developments in the tools we have available. Of course, we still use measuring tapes and dumpy levels but the GNSS, laser scanners and total stations combined with these tools gives archaeologists an amazing array of tools to work with spatial data.
There’s a full account of the history of surveying techniques in archaeology over on the Wessex Archaeology computing blog, here and my talk on these technologies is below:
I spoke about GIS, survey techniques and laser scanning and the online video includes some footage of a castle scan I’m currently working on. This footage of the laser scan data is a preliminary version of something that will shortly be available on the Wessex Archaeology website as part of some webpages relating to that project. There will be more on this here and over at the Wessex Archaeology blogs.
Laser scanning is becoming increasingly important as a tool for capturing 3D data relating to sites, monuments, buildings and even entire landscapes by using airborne LiDAR systems. Recent projects have been some of the biggest and most detailed to date and the upcoming web pages will reflect this; keep an eye on this site and the Wessex Archaeology blogs.
