In this paper it is proven beyond reasonable doubt that the pyramids and structures on the Giza plateau to the west of Cairo contain a sophisticated prime meridian layout which is the baseline for a survey grid which tessellates continuously around the world. The geometric creation of that grid is explained and it is proven that other ancient monuments are built to align to the survey grid. In the process of explaining the survey grid's design a series of locations on the Giza plateau are mathematically identified which correlate to the known surveying points of the plateau to within the tolerances of those surveys.

The coordinates of the corners of the Great Pyramid of Giza are located geometrically for the building's external stonework lines, the platform upon which it is built and for the external corners of the foundations of the building, known as the socket corners. From these corner points the azimuth of the casing sides of the pyramid are calculated and shown to agree to the surveyed value to within 0.63 of an arc second.

The boat pits that surround the Great Pyramid are resolved during the process of the analysis and are shown to contain the angular value of the tectonic plate movement of the African plate upon which the Giza plateau monuments are built. The discovery of an as yet unknown site in Egypt is explained which marks out the position of the sidereal day meridian relative to the prime meridian at Giza and it is shown that the external walls of the building at this location are a replica of the Sphinx temple's inner layout.

It is explained how the mastabas that surround the Giza pyramids have been designed to correlate to the geometric grid and the discovery is presented of the second Sphinx of Giza, which is situated to the south of the currently known statue and which is still buried under the desert sands. From this discovery the design of the Unfinished Pyramid at Zawiyet el­Aryan 3km south of Giza is deduced and the grid's dynamic grid rotation geometry is concluded at this location.

Finally it is shown how the grid tessellates around the world and that the principal row of statues on Easter Island at Ahu Tongariki align perfectly with the Giza grid design.
