The visualisations were produced from a Digital Terrain Model (DTM) based on LiDAR data provided by Bluesky at 25cm resolution. This DTM was also used to produce a Local Relief Model using one of the ArcGIS tools currently being developed by Archaeogeomancy for the National Trust. The LRM was then draped over the DTM, exported as VRML and uploaded to Sketchfab. Continue reading →
Prestonbury Castle, one of the best of the iron age hillforts that ring the edge of Dartmoor
Archaeogeomancy are very pleased to have completed this catchily named project for the National Trust (NT). The project involved working with LiDAR data produced by Bluesky in order to enhance the Historic Environment Records (HER) resources for the NT property and also produce some informative 3D visualisations of key monuments.

Whilst working for Wessex Archaeology, I was privileged to play a minor part in a project which, over the course of numerous seasons of excavation, has proven to be rather exciting. Under the careful management of Gareth Chaffey and Alistair Barclay supported by a broad team of field archaeologists and other specialists, the site at Kingsmead Quarry, Horton (Berks) has given plenty of evidence for life over the last 12,000 years since the last ice age, particularly for Neolithic through to Bronze Age activities.

The Digital Preservation Coalition and the Royal Commission on the Ancient and Historical Monuments of Scotland invite you to join them at a workshop to explore the preservation of 3d laser scan data.
Current best practice guidance for the long term preservation of 3D laser scan data, in particular the required metadata is found to be onerous by data creators. This workshop will bring together leading practitioners from the archaeological community, alongside leading data archivists and software suppliers in the UK and Ireland to work towards agreeing a new metadata standard to facilitate preservation.
This event will allow for communication between archivists, creators and purveyors of software and hardware for laser scanning, as well as equipment manufacturers. The aim is to ensure that the export of metadata is much simpler and more convenient for users. Continue reading →
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.
