alt Hacker NewsI'd very much like to see this done in the UK.
Also agents analyzing drought pictures, where many ancient UK structures seem to appear would be an easy win. I've never checked whether there's a comprehensive drought picture map of the UK.

The National Library of Scotland has LIDAR imagery for all of the UK. Go to https://maps.nls.uk/geo/explore/ then pick a LIDAR layer as the background. This motivated me to make my own high-res LIDAR images on my hobby site (https://solentmaps.uk/) of my home area using QGIS with free government data in order to uncover interesting things. It has old OS maps of the UK (1880s to date) with a LIDAR layer for my local area (south Hampshire).
The UK landmass is really quite small compared to central America. I'd be surprised if there are many substantial structures left - geophys has been around a long time.
It's been going on for years in the UK. https://www.theguardian.com/science/article/2024/may/27/hobb...
