Ripple Photogrammetry at Grand Falls Dune Field, Arizona, from February 2024 to July 2024
Ripple images of a small region within GFDF were acquired using a NIKON D250 DSLR camera, then processed through Agisoft Metashope professional photogrammetry software to create digital elevation models (DEMs) of the ripple field. The DEMs included here represent dates between 02-20-2024 to 07-25-2024.
The photogrammetry component therefore comprises seven zipped folders, each containing a DEM (digital elevation model), an orthomosaic, colorized shaded relief (all TIFF files), and a processing report (PDF) labeled with the day data was collected.
