Inputs
elevation of first station (m)
m, for closure check
Format per row:
id, type, reading [, type, reading...]. Types: BS back-sight, FS fore-sight, IS intermediate. A turning point has both FS (closes prev. setup) and BS (opens next setup) on the same row.
Method & checks
- HI method: HI = RL_prev + BS; RL_next = HI − FS (or − IS for intermediate, RL stays @ HI − IS).
- Arithmetic check: ΣBS − ΣFS = Last RL − First RL.
- Loop closure: e = Computed Last RL − Known closing RL. Tolerable ≈ 12 mm·√K (K = km of leveling).
