No, they do not. There are three main pyramids in Giza, out of Cairo. Egypt has other pyramids, but they do not in any way resemble a map of the barred spiral galaxy that is our beloved Milky Way. The Milky Way contains roughly 400 billion stars.

The Milky Way was long thought to be a "spiral" galaxy much like the Andromeda Galaxy . But recent observations indicate that the Milky Way is probably a "barred spiral" galaxy. Viewing the Milky Way from within as we do, it is somewhat difficult to get a clear picture.

They use powerful devices such as the Hubble Space Telescope, and infrared and ultraviolet waves. Astronomers also use the direction of the path of light, gamma rays, and beta particles to study the center of our spiral-shaped Milky Way Galaxy.
Astronomers use infrared light to map the dust in between stars.

Constellations are strictly human inventions. Each one is a pattern that the brains of people see in the brightest stars. All of those bright stars are relatively nearby neighbors in our part of the Milky Way galaxy. Astronomers now divide the map of the sky into 88 areas, each of those named for the constellation enclosed in it.
A map in the shape of an oval is called the Mollweide Map.

Mathematicians and astronomers use the Azimuthal or polar map.
No, because it will be impossible for astronomers to survey at least 100 billion galaxies (each with 100 billion stars) to make a 3D map of the observable universe.
