Photogrammetry and the quantification of volume in stone artefact analysis: experimental improvements to the volume ratio. Stacey Middleton, Rebecca Phillipps, Joshua Emmitt The use of three-dimensional (3D) modelling in stone artefact analysis using laser scanning or photogrammetry has provided methods to enhance the accuracy of artefact quantification. Shape morphology and measurement are a central element to classic stone artefact analyses, and current studies focus on quantification at the individual artefact level through morphometric analyses. However, quantification using three-dimensional methods at the assemblage level has not yet been thoroughly explored. The volume ratio is a method developed by Phillipps (2012) that uses the loss of volume of an assemblage as a proxy for artefact transport and therefore human movement. This research uses experimental assemblages to test different methods of volume calculation including photogrammetry, mathematical formulas, and density.
