Hello
I have been forced to use a total station for some of the cave surveys I
am doing due to the amount of metal/electricity in the cave.
The total station records absolute angles, (in degrees and minutes)
which therion does not process. So 320 should be interpreted as -40
therion: error -- Entrance.th [53] -- gradient reading out of range --
321:49
however a quick check and survex does, but gives a warning, should
Therion not also do this, it would save me having to do a tedious
conversion.
(Survex does not understand degrees and minutes but that is not really
relevant)
Example part of the file
1.0 1.1 1.56 - up 0 is steel pin in tarmac, first 4X marking
#Tony's notes, azi and bearing swapped, but as this is the DistoX leg,
it must be the corrected version
#1.1 1.2 38.463 87:52 90:22 2 is Coxs Entrance
#corrected version form DistoX [AA: April 13]
1.1 1.2 38.463 90.2 3
1.1 1.3 18.132 137:38 83:07 3 is Ladye Chapel Entrance & WIS fixed
