3D GLG

3D GLG

This collection of 3D models of geologic strata and structures was created using structure from motion (SfM) photogrammetry from multiple still images in the Northern Arizona University Sedimentary Geology laboratory using Agisoft Metashape. Credit to NSF for funding this effort. See https://en.wikipedia.org/wiki/Structure_from_Motion for more information on how SfM works. These models are offered for free for all for non-commercial purposes. To view these models in 3D, use the free Adobe Acrobat Viewer. First save the linked PDF file to your computer. Second, open the file then, under options, select ‘trust this document’, and finally, click once on the screen to make the model appear. Use the shift and control keys to navigate. By right clicking on the screen, activate the ‘3D measurement tool’ from the tool toolbar to measure distances, fault separations, stratal thicknesses, etc…

Cyclothems of the Pennsylvanian Morgan Formation exposed in the canyon of the Yampa River, Dinosaur National Monument, Colorado. Alternating intervals of blue-gray limestone and orange cross-stratified sandstone record repeated glacio-eustatic sea level fluctuations. Photosets acquired from raft.
