This is a 10 million to 1 scale of SRTM 90m elevation data with a ten times vertical exaggeration. This is far more challenging than it needs to be. I'll document the process when I figure it out and produce a decent printable model. Instructions These steps provide a rough outline of the methods used to create this file, largely based on the following guide: https://dl.dropboxusercontent.com/u/11089897/3druckench/maps_to_3D.pdf Download 3DEM from http://freegeographytools.com/2009/3dem-website-is-gone-but-3dem-still-available-here Open 3DEM: [File] -> [Load Terrain Model] -> GeoTiff DEM (tif) -> Load your geotiff (from the Thing files) [File] -> [Save as USGS ASCII DEM] -> Save as USGS DEM File (*.dem) Download AccuTrans3D from http://www.micromouse.ca/downloads.html Open AccuTrans3D: [File] -> [Open DME as] -> [USGS 1-degree (ASCII) (*.dem)] -> Open file.
