LiDAR, Local Relief Models and Sketchfab

Cranbrook Castle; LiDAR based Digital Terrain Model (DTM)

Cranbrook Castle; LiDAR based Digital Terrain Model (DTM)

The following visualisations were produced as part of the Fingle Woods and Castle Drogo Aerial Survey Analysis and Interpretation project, recently completed for the National Trust. There is a visualisation for each hillfort in the study area: Prestonbury Castle, Wooston Castle and Cranbrook Castle.

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

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.

When Prehistoric Farming Begins: Kingsmead Quarry, Horton

Archaeological excavations in a quarry

Archaeological excavations in a quarry

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.

Digital Past 2014

Laser scanning

Laser scanning a historic building

The call for papers is now out for the Digital Past 2014 conference, now in its sixth year. Time really has flown since I was privileged to speak at the first conference back in 2009 and the conference has grown in strength year on year. The main themes this time are Technical Survey and Deliverables, two excellent subject areas. Continue reading

3D Laser Scanning: Seeking a New Standard in Documentation

Terrestrial Laser Scanning (TLS)

Terrestrial Laser Scanning (TLS)

The Digital Preservation Coalition (DPC) and the Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS) are organising a workshop to look at the preservation of laser scan data.

The event is described thus:

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

Archaeological survey at Sandsfoot Castle; recording one of Henry VIII’s castles

GIM 09/2012 cover featuring Archaeological Survey at Sandsfoot Castle

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.

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.

St Andrew’s, Holcombe – geomatics and geophysics in action!

Archaeological Survey at St Andrew’s Church, Holcombe, Somerset

Archaeological Survey at St Andrew’s Church, Holcombe, Somerset using Global Navigation Satellite Systems (GNSS), Total Station Theodolites (TST), Terrestrial Laser Scanner (TLS) and Reflectance Transformation Imaging (RTI)

There are still some places left on tomorrow’s geomatics and geophysics and RTI events over at St Andrew’s Church, Holcombe, Somerset; see the project website for full details.

And don’t forget there are a whole series of talks, opportunities to speak to some real life archaeologists and a flying demonstration of Unmanned Aerial Vehicles (UAVs), all on this Saturday afternoon (21st July).

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

Archaeological Computing Research Group Seminar, May 23rd 2012

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.

CAA – presentations

Anxiety discourse by Jeremy Huggett.

Anxiety discourse by Jeremy Huggett.

Well, conference over, dust settled, time for some reflection. Overall, another rip-roaring success with some really interesting talks and a thoroughly entertaining plenary from Jeremy Huggett (as blogged by Orla Murphy). Social media was everywhere this year and whilst there is still room for imrovement in how such channels are integrated into the conference as a whole, this years organising committee have certainly set the bar high for Perth next year.

A fuller review of the sessions I was involved in is forthcoming, but in the meantime, my talks are all now online on Slideshare and presented below.
