Topographic Tutorial: Pentagon Area

This model is a first download of an area using the University of Iowa's TouchTerrain service here: https://touchterrain.geol.iastate.edu/

In this model, we centered on the location of the Pentagon, a military headquarters, near Washington, DC, USA.  Bounding box goes from upper right: (38.89101366263339 N, -77.02700035458454 E) to lower left: (38.85091899757407 N, -77.0832480657662 E).  The underlying data has 10m resolution on the digital elevation data.

The vertical elevation scale factor was set to 5, to exaggerate the vertical distances.  The model base was set to 0.5 mm to limit wasted base material (default is 1mm).

Other parameters were left as default on the web page for generating the STL.
