Deltapodus 3D models from Belvedere & Mietto 2010

Here we provide the 3D models used to generate the false-colour maps, the contour-lines and the cross-sections in Belvedere and Mietto, 2010.<br>The two tracks were moulded in the field with silicon rubber (Silical 110 – CTS srl), from which fibreglass casts were made. A triangulation-based laser scanner ShapeGrabberSG1002 was used to digitize the two fiberglass casts, and all the subsequent data manipulation was carried out with Innovmetric Polyworks, following the method of Petti et al. (2008).For each fspecimen, we performed five scans at 0.3-mm resolution, which were then combined, achieving a final standard deviation of 0.11 mm.<br><b>References</b><br>Belvedere M. and Mietto P. 2010.

本研究提供用于生成Belvedere与Mietto（2010）研究中假彩色地图、等值线及剖面的三维模型。
本研究通过野外硅橡胶（Silical 110 – CTS srl）对两处足迹进行翻模，进而制作玻璃钢铸型。采用基于三角测量法的激光扫描仪ShapeGrabberSG1002对两处玻璃钢铸型进行数字化建模，后续所有数据处理均遵循Petti等人（2008）的方法，使用Innovmetric Polyworks软件完成。针对每个标本，我们以0.3毫米的分辨率进行五次扫描，随后将扫描数据合并，最终得到的标准偏差为0.11毫米。
