[Therion] FW: Source and Select

[Bruce]

I just found the message below on GMANE.  My spam filter must have prevented
me from getting it.
 
I agree absolutely with your comments Martin.  That is why I fell in love
with the idea of Therion before I even tried it.  
My comment in brackets below was trying to address possible pitfalls to the
change to Therion that I was suggesting at the time (a single run gives a
consistent output set).  I come across some surveys and drawings that we
have entered into Therion that from the outset should have been thrown away
BEFORE considering data entry.  That bad.  But of course, something is
better than nothing, so we entered and drew it.  If in the future someone is
so annoyed, and a re-survey is done, they would be better to abandon
(archive) the whole survey (for that part of the cave - not the whole
system) and start again.  Definitely NOT the Therion way, (and not my way)
but sometimes you have to cut your losses and start again.

It is not the best idea as I understand the therion. re-survey means  
for me "to correct the errors of former survey". In that case you just  
correct surveying legs data and drawings in situ. Later you do the  
same in data editor (comment old data) and in map editor with old  
version archived.
 
Therion=never do the same again. Or therion=data will never lost.
