On October 28, 2018, I learned that author Manu Seyfzadeh, who has posted on this discussion forum received an email by Glen Dash informing him that. . . .
‘The center of the base of the Great Pyramid is at N100,000.023 and E499,999.987 according to our latest estimates.’
So, taking the above Northings and Eastings for the ground-level center of G1 provided by Glen Dash, Manu Seyfzadeh, calculated the center of the Great Pyramid on February 26, 2018 at the base ground level in degrees, minutes, and seconds, as 29°58′45.04802″N, 31°08′03.12389″ E.
In decimal degrees these same coordinates are 29.97918001°N, 31.13420108°E.
Below is an aerial view diagram of the truncated summit of the Great Pyramid of Giza and the coordinates of its center at ground level on February 26, 2018 of 29.97918001°N, 31.13420108°E. Diagram by Manu Seyfzadeh.
I have framed the ‘Base Center’ data pertaining to the center of G1 (Great Pyramid) at ground level in 2018 within the box (bottom right).

In 2015, Glen Dash determined the S/E corner coordinates of G2 at 29°58'30.04"N, 31°7'54.69"E in degrees, minutes and seconds.

The image above, which includes these coordinates for the S/E corner of G2, as were determined by Glen Dash in 2015, and was taken from his 2015 Map survey of Giza file, were kindly passed onto me by author and friend Dr. Manu Seyfzadeh on January 10, 2021.
The coordinates of 29°58'30.04"N, 31°7'54.69"E in degrees, minutes, and seconds, convert to eight decimal places in decimal degrees as 29.97501111°N, 31.13185833°E.
To keep the coordinates consistent with the coordinates of G1 in 2018, I discovered that around 2018, these same coordinates for the S/E corner of G2 would have slightly changed in their last digits to 29.97501118°N, 31.13185885°E in decimal degrees, and 29°58'30.0402", 031°07'54.6919" in degrees, minutes and seconds.
I was able to work out the other latitude coordinates from the significant distances between the center of G1 at ground level and the original south-base casing edge of G2 (based on coordinates the S/E corner of G2) using the Vincenty Distance calculator.
This accurate online ‘distance calculator’ is based on the formula devised by Polish American geodesist, Thaddeus Vincenty [1920–2002], which gives the ‘MAP LENGTH’ distance in METERS between two points on an ellipsoidal earth model accurate to within 0.0005 of a meter, which is only 0.5 millimeters or 0.000015 of an inch.

What I have termed the "Golden Cut latitude" runs through Giza, dividing the N/S longitudinal distance between the center of G1 in the north and the center of G3 in the south into the Phi-ratio proportions of 1 and 0.618.
The African Plate on which Giza is situated is slowly moving at the rate of 2.15 cm per-year in the northeasterly direction of 51.46 degrees azimuth, and this has been consistent over the last 100 million years, and so the GPS coordinates of various key points of the Giza monuments will change slightly over time.
Using both the Vincenty Distance Calculator and the UNAVCO GSRM v2.1 calculator - one of the most accurate Plate Motion Calculator’s I have consulted after studying all those that are available online - I was able to project the 2018 coordinates back 38 years to 1980, to find the most significant findings relating to the numbers in the Golden Cut latitude at that time, which generates the inverse number of the Fine-Structure Constant to the full 12 digits (nine decimal places) (137.035999084) as was determined in 2018 by physicists and published by CODATA on May 26, 2019.

We simply multiply the numbers in the Golden Cut latitude of 29.9766248 by 4.5714285714 (32/7) to obtain the first 12 digits of the result, which is 137.035999084.

The result of 32/7 being 4.5714285714 turns up elsewhere at Giza:

Based on the measurements made at Giza by Sir William Flinders Petrie between 1881 and 1882, Giza researcher, John Legon, diagrammed the relative positions of the three main pyramids at Giza and their royal cubit measurements and distances from each other, as follows:
![]()
As we can see John Legon gives a distance of 250 royal cubits between the original south-base, casing-edge of G1 and the original north-base, casing-edge of G2 - although the true distance is really 251.48205 royal cubits.
If we take Legon's distance of 250 royal cubits, this would mean that the distance between the original south-base casing-edge of G1 and the Golden Cut latitude would be 320 royal cubits, and the north-base casing-edge of G2 to the Golden Cut latitude below it, would be an all-round 70 royal cubits.
![]()
The result of 320/70 is also 4.5714285714, and so we are given a clue here to the numbers 320 and 70 in the measured distances between G1 and G2 and the Golden Cut latitude - the result of 320/70 - i.e., 4.5714285714 being used to generate the inverse number of the 2018 Fine-Structure Constant determination via the 29.9766248 number in the Golden Cut latitude relating to 1980.
But as we can see, and as revealed in the 2018 and 1980 images of Giza above, the Golden Cut latitude passes through G2 at the distance of 71.752 meters (137.0359 royal cubits) north of the center of G2, and also half the distance of 137.0359 royal cubits (68.48205 royal cubits) south of the original north-base casing edge of G2. 137.0359 is the first 7 digits (four decimal places) of the inverse fine structure constant.

71.752 meters divided by 0.5236 m (one royal cubit) = 137.0359 royal cubits.

35.876 meters divided by 0.5236 m (one royal cubit) = 68.51795 royal cubits (137.0359 / 2).

In the whole timeline of human history, 1980 was the only year that the numbers in the Golden Cut latitude of 29.9766248 at that time passing through Giza, would generate the full 12-digit number of the inverse Fine-Structure Constant that was determined by physicists in 2018.
