About Manassas, Virginia
The First Battle of Bull Run, called the Battle of First Manassas by Confederate forces, was the first major battle of the American Civil War. The battle was fought on July 21, 1861, in Prince William County, Virginia, just north of what is now the city of Manassas and about thirty miles west-southwest of Washington, D.C. The Union army was slow in positioning themselves, allowing Confederate reinforcements time to arrive by rail. Each side had about 18,000 poorly trained and poorly led troops. The battle was a Confederate victory and was followed by a disorganized post-battle retreat of the Union forces. Just months after the start of the war at Fort Sumter, the northern public clamored for a march against the Confederate capital of Richmond, Virginia, which was expected to bring an early end to the Confederacy.

It also works for CNC carving. Use Customize to change the width, base thickness or height exaggeration, make it round or add a name plate.
How accurate is the Manassas model?
It is built from real elevation measurements, not an artist's guess: the USGS 3D Elevation Program, mostly airborne laser scans at 1 to 10 meters per point. The shaded picture on this page is made from the same data.
Is the Manassas model free?
The Standard resolution model is free as STL, 3MF, Colored 3MF, OBJ and a 16-bit heightmap. High resolution samples the place about ten times more finely and is a paid upgrade.

About this terrain model
Embossify Terra builds Manassas, Virginia from real measured elevation, not an artist's guess. In the United States the heights come from the USGS 3D Elevation Program, mostly airborne laser scans that resolve every 1 to 10 meters.
The model covers a 10 by 10 kilometer square centered on 38.8120, -77.5210. It prints 150 mm (5.9 in) wide on a solid base, a scale of about 1:66,700. The heights are exaggerated 2× 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.
