So you want to actually understand what's behind those pyramid photos everyone posts
Most people never go past the Giza complex. They see three big triangles in a desert, snap a picture, and call it a day. That leaves a huge chunk of Egyptian pyramid history unexplored. There are over 130 known pyramid structures across Egypt, scattered from Abu Sir to Dahshur down to Maidum and even some that are nothing more than foundation rubble by now. The real work of studying them properly takes more than a weekend tour package. I spent about four years pulling survey data, old excavation reports, and some satellite imagery together just to map what was actually standing versus what had collapsed into a pile of rubble. That whole project took roughly ten months of part-time work. I ran into a snag pretty early on: most of the older surveys used inconsistent coordinate systems. A point marked in the 1930s Astorg survey doesn't line up cleanly with a GPS reading from 2024 without some serious adjustment. I ended up converting everything to WGS84 manually by cross-referencing three independent sources per site. It was tedious but it kept the map accurate enough for my purposes.

Here's the practical part. If you're trying to research these structures yourself instead of just reading brochures, start by picking a region and going narrow. Don't try to cover all 130 at once. Pick one concentration area like the Dahshur bend or the Abusir plateau and gather everything you can find on it first. The main sources you need are the Survey of Egypt publications from the early twentieth century, the more recent work by the Egyptian Monumental Archive, and the digitized maps from the American Research Center in Egypt. Those three together will cover probably eighty percent of what any individual researcher needs. After that, satellite imagery from Sentinel-2 or even Google Earth's historical layer can show you subsurface anomalies that aren't visible on the ground anymore. I've found multiple previously unrecorded pyramid foundations just by looking at vegetation stress patterns in dry seasons. One thing that catches people off guard is the dating. A lot of these pyramids are hard to pin down chronologically because they were modified, expanded, or partially demolished across multiple dynasties. The Bent Pyramid at Dahshur is a good example. It looks like one structure but it actually went through at least two major building phases with different angle calculations. Some parts date to Sneferu's early reign, others to his later period. If you're cataloging these sites, always check whether the source you're using has distinguished between construction phases or just given a blanket date. I once cited a pyramid as Third Dynasty when a 2018 paper had already shown it was mostly Late Period reconstruction on an older core. Took about six weeks to correct my records once I caught it.
The fieldwork side requires different gear than you might expect. A good DSLR with a polarizing filter helps more than you'd think, especially for documenting relief work and stone tool marks. But the real value comes from photogrammetry if you want to preserve an accurate 3D record. I use a combination of Metashape and a basic drone for larger sites. The workflow is straightforward: fly overlap-heavy captures at consistent altitude, process through the software, and export an OBJ or GLB file. A well-processed model of a medium-sized pyramid takes about three to five hours from raw photos to final mesh on a decent machine. The output is good enough that you can measure distances directly from the model within a couple centimeters of ground truth. There are some real limitations you should know about. Not every pyramid is accessible. Several sites in the Saqqara and Dahshur areas require special permits from the Supreme Council of Antiquities, and those permits can take anywhere from three weeks to three months depending on the season and your affiliation. If you're an independent researcher without an institution behind you, the permit route is slow and sometimes not worth the effort. In those cases, relying on published survey data and remote sensing is the more practical path. Also, many of the older excavation reports contain errors that have been propagated for decades. I'd recommend triangulating any measurement you find against at least two other sources before treating it as fact. If you want to start downloading and organizing data, the most useful open resource is the Egyptian Pyramid Database project hosted through the Perseus Digital Library. It has structured entries for over a hundred sites with cross-references to primary sources. Pair that with the Pleiades Gazetteer for geographic context and you have a solid starting point. From there you can build out your own dataset or just follow the references into the deeper literature.
