These models are terrain models of Yosemite Valley, California, featuring Half Dome, El Capitan, and the surrounding granite formations in Yosemite National Park. They were generated from USGS elevation data to accurately represent the real-world topography of the region.
Elevation data was obtained from the United States Geological Survey (USGS) National Map (https://apps.nationalmap.gov/downloader/) and downloaded as GeoTIFF elevation files covering the Yosemite Valley area. USGS data is in the public domain.
The GeoTIFF files were merged into a single elevation dataset using QGIS:
Load all downloaded GeoTIFF files into QGIS.
Open the merge tool:
Raster → Miscellaneous → Merge
Select all DEM tiles as input layers.
Leave elevation values unchanged (Float32).
Run the tool to create a single merged GeoTIFF.
The merged elevation raster was converted into a STL using an add-in for QGIS. A helpful tutorial demonstrating this workflow can be found here:
