In this document, we describe the surveys we have made available for display on Google Earth.

To start, open one of our files in Google Earth. Clicking on an icon will bring up a bubble showing the latitude, longitude and elevation of each point above mean sea level. It also shows the location of each point on the Giza Mapping Project (GPMP) survey grid. If a picture of the point surveyed is available, that is displayed as well. Some bubbles will include additional information, such as related files, drawings, sketches, maps, and/or a description of the point in question.

Note: Check the file names below to make sure you are using the latest data!

Giza Pyramids Corners and Centers

Latest File Name: Giza-Corner-Points-2v17.kmz

Replaces Giza-Corner-Points.kmz

This file contains our best estimates of the locations of the original corners and base centers of the three largest pyramids at Giza: Khufu, Khafre and Menkaure. The original corners no longer exist so we used the best available data to project their locations. In the case of the Great Pyramid of Khufu we used the data from the Glen Dash Foundation Survey of 2015 (GDFS 2015). [2] In the case of Khafre and Menkaure, we used data from Flinders Petrie’s 1880-1881 survey. [3]

We have also plotted the locations of the survey control points used in the GDFS 2015 survey, G1.1, G1.2, G1.4 and Point W-NW. G1.1, G1.2 and G1.4 are bronze markers left by previous surveyors. Point W-NW is a "reference mark" left by Flinders Petrie to the north and west of his Station W. [4]

Robin Cook provided the elevations we used, based on surveys by Petrie and Maragioglio and Rinaldi.

Glen Dash Foundation Survey of 2012 (GDFS 2012)

Latest File Name: GDFS-2012.kmz

This file plots the survey data from the Glen Dash Foundation Survey of 2012 (GDFS 2012). Details on that survey can be found at:

GPMP Full Circle

To help locate points, we sometimes identify them on survey plans prepared by previous surveyors. In the balloons we refer to these plans as "sketches." Here they are:


Flinders Petrie's Stations

Latest File Name: Petries-Stations.kmz

This file plots the "stations" used by Flinders Petrie in his 1880-1 survey of the Giza Plateau. These stations were his control points for the survey. [5] We have also plotted places where he found evidence of the casings' bases and his derived centers and corners points for the pyramids.

Robin Cook provided the elevations we used, based on surveys by Petrie and Maragioglio and Rinaldi.

Details on the derivation of this data can be found at:

Petrie's Indelible Marks

Glen Dash Foundation Survey of 2015 (GDFS 2015)

Latest File Name: GDFS-2015-Master-25iii17-edited-child.xlsx

This is the data from our 2015 survey at Giza.

You can also bring up the key by clicking once on "Key" under the file name in places.

GPMP Control Monuments

Latest File Name: GPMP-Control-Monuments.kmz

This file plots the control monuments used by Ancient Egypt Research Associates in mapping the Giza Plateau. The control monuments make up the Giza Plateau Mapping Project (GPMP) control grid.
