Walls and underwater Survey

[rchrds]

Ok- I was pretty sure I read this in the manual somewhere, but for some reason, today, I can't find it. What is the notation in the #units directive that will let me use negative numbers to denote depth below the surface of the water in place of a clino reading?

Thanks!

Don't feel too sorry- I gave up on the sketching and surveyed 1120 of 1600 feet of virgin underwater tennessee cave we found on Saturday...And left the tie-off in virgin borehole....

Maybe after my life resumes in October, I'll be able to get down to TN (or KY) and see some virgin cave myself..... if there's any left!!!

I will post the reply to my own question, so someone after me can have the answer-

Here is the format for underwater depth readings:

#units feet order=DA Tape=SS
;from to dist AZ From Depth TO Depth
1 2 43 139 0 34
2 3 12 151 34 40
3 4 89 159 40 82

etc, etc.
all depths are positive numbers. Not sure why it works, but it does.

I have used Walls for underwater surveys in Roppel, using HF/HT (Instrument/target heights). I was going to send you the Walls file with a sample, but would help if I sent the original book scan, which I will do when I return from Taiwan.

wow, you're just down the sea from me, drop by if you can!
