3D Landmark data on grey seal skulls for the article "Measurement error using a SeeMaLab structured light 3D scanner against a Microscribe 3D digitizer".<div><br></div><div>The landmarks were measured in two different ways:</div><div>1) Directly on the skulls using a Microscribe 3D digitizer</div><div>2) On the 3D surface models of the skulls based on structured light scans using the Stratovan Checkpoint software. The 3D models are available on Morphosource: <a href="https://www.morphosource.org/projects/000355763">https://www.morphosource.org/projects/000355763</a>.</div>
