For the training exercises, I could own a collection or a series of digital surface models (dsm), relative to every single step or excavation phase on the excavation's site process.
Lluís, Your description looks similar to what mining geologists do to provide an estimate of ore by grade and location; a 3D model of the ore body based on core (or bulk) samples. A less expensive approach than using a LiDAR-equiped drone would be to take depth measurements at points on a defined grid and use geostatistical models to interpoate between unmeasured points. If you need to only map strata, grass has capabilities for producing 3D models of geology but I've not used them because I'm not a geologist. Something to consider while others provide more explicit ideas.
