This sounds like a classic survey problem. Tools that deal with this are
often called COGO (I don't remember what that means)
While many tools and algorithms exist for doing distance and bearing,
which will allow to you plot changes in x,y of whatever plane you're
working in, the z value would need
Tom,
You have laid out an interesting (fun) problem. I don't have a
solution for you, but a few thoughts on how I would approach it.
1. I am not sure how you want to display the 3D shape in QGIS. If
you are just going to symbolize the depth by coloring the line
segments, you could get by with
Okay, let me rephrase the question. I did look at ogr2ogr, csv file
