This is the companion document and data archive for **Zhang C. and Maga AM (2023) An open-source photogrammetry workflow for reconstructing 3D models. Integrative Organismal Biology** (https://doi.org/10.1093/iob/obad024). It provides the instructions for how to setup the workflow, sample photosets, reconstructed 3D models and their associated landmark sets used in the analysis. **Google Drive folder** provides the latest set of step-by-step instructions for the workflow. Should the document fail to load through the inline viewer, you can access [the same document via this link][1] **Photos:** folder contains an example set of photographs taken for the from the skull of UWBM39384. **39384_raw_photos.zip** contains images as acquired by the camera; while **39384_masked_photoz.zip** contains the masked images via our custom python script. These are the images, along with the marker coordinate file, that were submitted the WebODM to obtain the 3D textured model. See the accompanying SoM for exact settings used in WebODM. Make sure to pool all images in a single folder prior to uploading to ODM. **Landmarks:** folder contains three sets of landmarks collected from each model, as well as their means. **MicroCT Volumes:** folder contains the microCT scans of the beaver skulls used in the study. While acquired at 35 micron resolution, microCT volumes were downsampled to 50 micron to manage file size. NRRD is an open-source file format for N dimensional arrays that preserves correct geometry of the acquisition. It can be directly loaded into 3D Slicer, or imported in to FiJI/ImageJ or can be opened in Python using pynrrd library. **Models:** folder contains the 3D models generated by ODM as well CT. **3D Models are in PLY format** and **landmarks coordinates are in MRK.JSON format**. Both of these formats can be loaded into open-source 3D Slicer biomedical visualization platform (available for free at https://download.slicer.org) **_ODM** suffix indicates that the 3D model has been derived from the ODM photogrammetry pipeline. **_CT** suffix indicates that the 3D model has been derived from the microCT scanning of the same specimen. Texture information from the photogrammetry pipeline **_ODM** is baked as vertex color using the MeshLab software. While this degrades the texture detail somewhat, it makes the data files more portable.
