3D Model of Lost Civilizations from LiDAR Data

digital twins of lost civilizations fascinate me hearing about PhD students discovering previously unknown cities in old aerial LiDAR collections from Mexico really makes you wonder - how much more would we learn about our own history if we had a true 1:1 3D model of the world? alas, right now it's a patchwork. islands of high fidelity stitched together with coarser maps of everything else. and that's just land - the oceans of course are an even deeper mystery
