The good folks from the Spatial Humanities Project based at Lancaster University are running a free one day seminar in November. This is only part of their outreach activities which also feature an informative YouTube channel and other learning resources. Continue reading
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.
For more information on the project, see the Wessex Archaeology case study.
For more information on the castle itself, see the website of the Friends of Sandsfoot Castle and the Rodwell Trail.
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
It is indeed interesting that this post on Doug’s Archaeology regarding jobs in archaeology, specifically management jobs in archaeology, mentions GIS. GIS skills/qualifications in archaeology is a particular area of interest of mine.
In the UK, GIS is used for many tasks from resource management (eg Historic Environment Records) to undertaking Desk Based Assessments (DBAs) and Environmental Impact Assessments (EIAs). As such, a requirement for GIS appears more and more often on job adverts in the public and commercial sectors, at least for jobs that involve ‘doing’ rather than ‘managing’. True, management jobs typically do not mention GIS unless they are considered ‘technical’ posts. This often means archaeology managers are responsible for staff who use GIS yet may not understand or appreciate what their staff are doing. 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:
Some of my colleagues and I were recently interviewed by the Institution of Engineering and Technology about our work and a video to accompany the magazine article is now online as reported by Wessex Archaeology.
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.
