Hi, I’m Helen. I’m actually a computer scientist rather than an archaeologist, working on a project called `HeritageTogether’, which is all about creating 3D models of prehistoric sites in Wales. The project is run jointly between archaeologists and computer scientists at Bangor, Aberystwyth and Manchester Metropolitan Universities – I work as a researcher in Aber.
We are making the models using photographs of the site and a process called photogrammetry which matches up the features in photographs and can automatically create the model. While the project is mainly based on photographs contributed by the general public, we sometimes go out to survey some sites ourselves.
To help with our surveying, we have an Unmanned Aerial Vehicle (UAV) – a remotely controlled flying vehicle that carries a camera; a hexacopter (it has six rotors) to be specific.
Today, Andrew, Joe, Jonathan and I were visiting two sites on Anglesey in North Wales – the Lligwy burial chamber and Din Lligwy settlement near Moelfre. Two beautiful sites which are well worth visiting.
