0) Follow Patrick Warren's Workflow advice. (ReadMe.md in https://github.com/patrickbwarren/inkscape-survex-export/releases/tag/v2.0)
1) Some guesses for height in the alcoves. Length = 35m main chamber + alcoves
2) Think about how LRUD will look. Not each station needs it. (Left, Right is at right angles to the leg)
3) It's more or less horizontal.
4) "Tape" or instrument at waist height, so 1m down.
5) Some definite 'artistic' licence. Survex / LRUD is not the smoothest passage outliner.
6) Presumed GR is centre of entrance (stn 1)
7) Date is 2003?
8) *CS UTM30N
