[Therion] "ignoreall" is getting ignored DATA ORGANISATION

[Bruce Mutton]

As an aside to the post below, and from the perspective of data
organisation...

I started my Therion 'life' using the 'more correct' syntax below, and ended
up with data files about as difficult to read, and hard to check against
field notes (which have offset lines to distinguish between leg data and
point LRUD data) This syntax blurs the distinction between LRUD for the
'from' station and the 'to' station, compounded by the Therion convention of
defaulting to the 'to' station unlike other software (typically American)
common in New Zealand.

Luckily, as it turns out, not knowing about the '-' option meant that I
settled on an approach that completely separates the two dimensional leg
data from the somewhat one dimensional point LRUD data.  This has turned out
to be much easier to enter, check and correct, and looks much tidier.  The
small amount of extra typing is well worth it, and for that matter, Therion
does most of the extra 'typing' for you.
For example...

   #Survey Legs
   #-----------   
   data normal from to tape compass clino 

    F38  F39   5    245   -25  
    F39  F40   3.5  195    -5  
    F40  F41   4.4  236     0  
    F41  F42   8.1  205     3  
   
   #Passage Dimensions
   #------------------ 
    data dimensions  station right left up down 

    F38   2   1   10  3.5
    F39   1   2   10  3   
    F710  3   2    1  0   
    F41   0.5 1   1.5 1   
    F42   1.5 2   2.5 3  

Having said all that, it's nice that Therion has lots of flexibility and
really good to know about the - to leave the data unspecified.
(Presumably it gives better results than setting the values to zero?)

Bruce

Use dash for incomplete LRUD data or change the definition of data.

data normal from to compass clino length left right up down

1 2 15 -5 4 1 2 3 0
2 3 30 5 2,5 - - - -

or (this is more correct)

data normal from to compass clino length left right up down

1 2 15 -5 4 1 2 3 0

data normal from to compass clino length

2 3 30 5 2,5

data normal from to compass clino length left right up down
