The Gallia Recreation
Photogrammetric model of the wreck site created by Brandon Mason at the Maritime Archaeology Trust.
The Gallia project is a partnership project done with the Maritime Archaeology Trust in the UK and the Forgotten Wrecks of the First World War project. This ship was recorded as part of the Forgotten Wrecks project and the Maritime Archaeology Trust (MAT) allowed us use of the photogrammetry model and the wreck photographs and diver video.
The diving on the wreck took place in 2015 just south of Bournemouth. The wreck currently lies in approximately 38 metres of water. The photogrammetric model was recorded over the course of two days by Brandon Mason at MAT, who then processed and refined the model in the photogrammetric software. It is the remains of a steam ship that was approximately 91 meters in length, built in Sunderland, UK.
Using the diver video and dive photos, as well as personal testimony from the divers at MAT, our aim was to create an interactive dive built entirely from optimised polygon models. We rebuilt all of the elements of the wreck, such as remaining hull form, debris, and artefacts, using the photogrammetry and pictures as a base. Following this we reconstructed the terrain, the visuals of the dive, and the dive particulate to try and re-create and showcase the site in situ to showcase to the non diving general public. The work on this is still ongoing, however a short demo video can be seen below.
