Three-Dimensional Structural Recording of HMS Investigator at 74° North
Given the excellent state of preservation of the Investigator, three-dimensional hull recording was a key aim of the 2011 survey. At the outset this posed significant logistical and archaeological challenges on account of the site’s remoteness and uncertainty over how much diving time would be achievable (if at all) due to ice cover. The project team travelled to the far north prepared for a range of methods from standard hand mapping to a novel underwater three-dimensional laser scanner. This paper will describe how the structural recording unfolded on site and how the methods adapted to underwater conditions. It will also describe an unexpected but fortuitous collaboration with Queen’s University (Kingston, Canada) in the post-processing of photo-mosaic imagery. This resulted in the creation of a digital photogrammetric model of the ship’s upper deck that consists of over four million three-dimensional measurements accurate to under 1 mm.
