About this terrain model
Embossify Terra builds Three Sisters, Blue Mountains from real measured elevation, not an artist's guess. Outside the United States the heights come from open satellite and survey data (NASA SRTM, Copernicus and national surveys), about 30 meters per point.
The model covers a 10 by 10 kilometer square centered on -33.7320, 150.3120. It prints 150 mm (5.9 in) wide on a solid base, a scale of about 1:66,700. The heights are exaggerated 1.5× so the shape is easy to see and feel; you can change that when you customize the model. The sea is flattened to zero, so land stands on a clean base.
