[Therion] Secondary station

[Bertrand Hauser]

Salut,

I think you can use the "flag" directive :
(extract from the THBook)
*flags ▷ set flags for following shots. The supported flags are: surface
(for surface measurements), duplicate (for duplicated surveys), splay (for
short side legs that are hidden in maps and models by default). These are
excluded from length calculations. All shots having one of the stations
named either ‘.’ or ‘-’ are splay shots by default (see also data command).
If flag is set to approx[imate], it is included to total length
calculations, but also displayed separately in survey statistics. It should
be used for shots, that were not surveyed properly and need to be
resurveyed. Also “not” is allowed before a flag.*

Example :

survey XXXX -title "Blablabla"

  centerline
    date 2017.10.01
    team "zzz ZZZZ" notes
    team "tttt TTTTT" clino compass tape
    units length meters
    units compass clino degrees
    data normal from to length compass clino
    flags duplicate
    0 - 1.39 30.0 -0.8
    0 - 2.56 344.8 -3.6
    0 - 3.46 313.9 -2.2
    0 - 2.13 270.4 1.5
    0 - 2.56 339.4 45.3
    0 - 2.43 276.2 26.0
    0 1 10.47 336.5 -46.1
    # ....
    # all the shots you xwant to exclude from cave total length
    # ....
    flags not duplicate
    # ...
    # the normal shots
    # ...
  endcenterline

endsurvey

When you export a survey-list, you can see the total of each length type
(surveyed, explored, duplicate, surface...).

Bonnes explos !
