Crocodile tracks and trackways: Photogrammetric models and photo datasets.

3D models and photosets of Crocodile tracks and trackways

The files in this dataset comprise zip folders containing a set of photos, and a  textured mesh, of trackways made by 12 species of crocodile.

The physical casts were originally described in:

Milàn, J. and R. Hedegaard (2010). "Interspecific variation in tracks and trackways from extant crocodiles." New Mexico Museum of Natural History and Science Bulletin 51: 15-30

The data presented here are newly generated photogrammetric models, along with the associated photo sets. The models themselves have been reduced in order to keep file size manageable, but all photos have been included at full resolution so that others can produce their own high-res models from them.

Included data are as follows:
