This is just an exercise in scanning through google earth images now right? They don’t have to deploy their own hardware to get aerial images right?

- hedgehog 4y agoI'm not sure about this specific case but generally commercial wide coverage satellite imagery is not high quality enough to reliably see these kinds of formations. I'd guess they contract some combination of imaging including LIDAR to get better images to work from. That lets you see through vegetation etc. Here's an example from Tikal: https://www.sciencenews.org/article/lidar-reveals-oldest-biggest-ancient-maya-structure-found-mexico https://www.sciencenews.org/article/lidar-reveals-oldest-big...
- deltarholamda 4y agoThe article explains. They are using drone footage and AI to recognize likely patterns. These geoglyphs (they think) are older than the classic Nazca lines as some of the designs are similar to people who were around before the Nazca people, around 200BC I believe, and the Nazca are somewhere in the 1000-1500 AD range. They are also on hillsides instead of on the plains, so they are susceptible to natural erosion. That's why they're using the AI to suss out likely designs from the "damaged" areas.
