Size and positions of the big Pyramids by Petrie.
The Queens pyramids size and positions from a combination of sources.
Maragioglio & Rinaldi, - Zawi Hawass and thanks to Dennis, Google Earth measurements.
Belt star positions from Stellarium. I used Alnilam’s current position today as it has not changed noticably for 10000 years.
It was all put together with Photoshop at a scale of 1 pixel = 10 inches. The smaller image is not as accurate with a scale 1 pixel = 50 inches.
