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.

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

CAA 2012 Southampton

Computer applications and quantitative methods in Archaeology (CAA) 2012

CAA 2012 Southampton

CAA 2012 Southampton

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

Interactive Landscape Relighting

There’s a short article in the Remote Sensing and Photogrammetry Society’s Archaeology Special Interest Group Spring 2011 Newsletter looking briefly at how archaeologists can investigate landscapes using digital techniques, co-authored by Tom Goskar and myself. Using Reflectance Transformation Imaging (RTI) techniques it is possible to look in detail at surface morphology of Digital Surface Models (DSMs) by creating Polynomial Texture Maps (PTMs) representing parts of or even entire landscapes which can then be dynamically relit, a process Tom has named Interactive Landscape Relighting. Continue reading

Heritage in 3D

Following on from my last post, I’ve posted my presentation given at this years CAA UK conference to Slideshare. The subject was the use of terrestrial and airborne laser scanning in heritage contexts and made use of a number of case studies from work, which will shortly be published on the Wessex Archaeology computing blog in more detail.
