Hi Lluis,
Hi Max,
a real 3d GIS for Archaeology is not available at the Moment. You may try
to create some 3d Volumes in Grassgis but your students will hate it !
It doesn't sound too much attractive... :)
I have also been Looking for a solution to this (I am archaeologist
myself). But for now I stay with CloudCompare in 3d!!! Sadly CloudCompare
has no Attributetable connected to Features and Stylingoptions as you may
have enjoyed in Qgis. So unfold some section from your 3d meshes in CC and
Import them to qgis (working in a fake section where the y-axis becomes
the altitude…)
where you can do classification Styling labeling etc.
I will take a look to Cloudcompare 3d (I've never ever heard nothing
about it because I'm not so familiar with 3d software and engines), and
then I will do the trick into QGIS.
I have been working like this for 5 years now in the German Archaeological
Institute, ist a pain in the ass sometimes, but the results are proper
phaseplans plan and section corresponding to each other. I hope we will
have a real powerful 3d GIS one-day...
Thanks for your ideas and for sharing you experience.
Kind regards,
Lluís
All the Best

Hi everyone,
Let me share some doubts and concerns regarding to a concrete
application of GRASS GIS to archaeology.
The point is that I would like to prepare some training exercises for a
group of archaeologists, and I'm dealing right now with the problem of
how to properly represent stratigraphic sections or cross sections over
an excavation site. I mean something like this:
stratigraphy
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. In a practical way,
that means that every time a stratum is removed, the archaeologists can
get a new digital surface model using a drone and a lidar sensor. Then
computing the difference between the previous dsm and the current one
(and so on, successively), they could obtain a collection of stratum or
layers to visualize it in a cross section diagram. I don't know if the
problem is enough well explained...
I've been reading and searching on the Internet for a while, about GRASS
GIS and stratigraphic/cross sections, but I've didn't find any hint
neither a clear clue about how to do it. So, the question is, is it
possible to get something similar to the previous or the following image
using GRASS GIS, as well as combined, with other tools or open source
software? Any answer, hint or clue will be really appreciated.

Thanks,
Lluís
