Thanks,
I know cave view, it is very useful.
I noticed that if you press with the mouse on any location it gives you the hight from surface.
There is a shading called  depth below surface, but it stops at 23m (by the way is this a bug?), I know that there there are places with far greater depth then 23m.
I'm attaching a screenshot with the problem.

Hi,

I never focussed on that but :
  • If i do not mistake, you have the info of the altitude of each station in the sql database of the cave/system you may export. You may need to use some sql and/python queries to extract what you want.
  • I am sure this is quite easy to compute, the last version of CaveView (https://aardgoose.github.io/CaveView.js/) is indicating that nicely. If your aim is to get the depth from the surface for only few points, you may tried tu use CaveView (Juste open a web page that is also using a CaveView Viewer, and then drag and grad your .lox file in the 3D viewer panel).

Cheers

Thanks Xavier,
it worked!

So , after converting the KML to SHP I have a polyline of the cave centerline & spalyes. 
What I'm aiming for, are the stations with the absolute altitude.
If I manage to get that, then I can calculate the relative depth of each station from the surface.

Hi,

For shp, I never tried.

For kml, I export the centerline + splays by exporting the model, not the map. For instance :
export model -fmt kml -o Outputs/MyCave.kml

Hope it helps,

Xav
