Australia

thingiverse

This is a STL file made from the Bathymetry of Australia. The map height has to be exaggerated for 3D printing. If the height was scale proportionally to the longitude / latitude scale (10cm wide for 5500km), the map would only be 0.14mm tall. That's the thickness of a sheet of paper. Map to scale: - Horizontal = From West to East, the map is approximately 5500km. - Vertical = From the deepest ocean to the tallest mountain, this map is only 8km tall. Greyscale image scale: - Black = -6000m - White = 2000m The coastline is exactly at 2/3 of the total height. This is how I created the STL file: 1. I created a greyscale image from the Bathymetry, using GeoServer. This step can also be done using QGis or ArcMap. 2. I created a STL file from the greyscale image using the png23d library.
