I'm not sure if it is a bug or not, but I noticed that if I have one or
more undated surveys I get a warning saying "Unable to compute magnetic
declination for undated surveys." However if all of the surveys are undated I
no
longer get this warning and the output is uncorrected for declinat
I would appreciate any suggestions regarding the best (easiest, quickest)
way to locate points on the surface that directly overlie survey stations in
the cave. For example, suppose we find a place in the cave with surface
debris and would like to examine the surface directly above for an ent
I reference a nearby station in my naming since there's not likely to be
more than a few features that need naming:

join M23swall:end M22swall:0
join M23overhang:0 M22overhang:end

Graham,
I've got the centerline and LRUD data all together in the same block, as in
"data normal station left right up down newline length compass clino" and
immediately before it "units length feet" but it still treats my input
numbers at meters instead of feet (for the LRUD). Olly's suggest
Thanks Bruce for the code, I should have found that myself in the wiki,
sorry. It's exactly what I needed.

I recently used Therion to produce a map for a short horizontal cave. The
cave is only a little over 100' long and the floor is almost level from one
end to the other. The "depth" information that Therion generated for the
legend is 3 feet even though some of the passage in the cave is 5 feet
