Chose the hand-drawn site map over the drone survey in Cairo, zero regrets

When we were documenting a small dig site near Giza last spring, I had to pick between paying $300 for a drone mapping pass or doing it old school with a measuring tape and graph paper. I went with the manual map because the terrain was too uneven for the drone's software to pick up the buried wall lines. Took me two full days but I caught a subtle alignment that the aerial photos totally missed, and the lead archaeologist confirmed it matched the original foundation plan.

Done the same thing in a couple of spots myself, and honestly the tape and graph paper always wins when the ground fights back. Those drone shots look great until you try to line them up with what's actually under the dirt, then they just give you a headache. Last time I went manual I found a corner the aerial sweep completely smoothed over, just a small offset in the stone work but it changed where we dug next. Two days of crouching and swearing is a fair trade for that kind of detail, especially when the site's too messy for the tech to behave. Plus you get a feel for the place that a screen just can't give you.

Ha, preach. The drone gives you a pretty picture, but it lies about the little stuff, and the little stuff is usually what bites you. I spent a whole afternoon re-finding a wall line that the aerial map had shifted by maybe a foot, and that foot changed everything about the next trench. Tape and pencil might make your back ache, but at least you know the numbers didn't get smoothed out by some algorithm. Keep doing it the stubborn way, it pays off every single time.
