<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

one I would be proud to have produced.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>It looks like a lot of work for a very
small section of cave, very detailed! Something we New Zealanders have
come to expect from European cavers.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I abandoned involvement in cave map
production early 1990s when it became obvious that centerline software and paper
map development had outlived it’s usefulness. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>In areas under active exploration we had
multiple disconnected maps with large gaps and lost data, and fulltime map
re-drafters who spent their life drawing and re-drawing cave maps as our
knowledge of the caves grew. These people burned out, and after some
years someone else might take over, but with lots of data lost in the mean
time. Sound like the storey on the front page of the Therion web site?<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I tried to make AutoCAD do the job that
Therion now does, but lacked time, knowledge and skill.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Therion is my savior! I’ve
waited over 15 years for you. My experience so far? You’re free,
have a dedicated development team, can be easily used collaboratively by a team
of cave surveyors, and so long as documentation is done along with the survey process
(not waiting 12 years like we have) should be no more difficult than doing it
on paper. And you can produce many versions of a map with little more
than the push of a button. There are a few minor shortcomings which have more
than the appearance of being considered and worked through.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>The considerable effort I have put in to
learning Therion so far is no more than it would have taken to draw my current
cave project on paper, and the bonus is that it is unlikely to be wasted time, provided
I save the install file with the data :) <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I consider all of my time put into paper
maps of cave systems (isolated caves less than 1km excepted) has been
completely wasted. They are all obsolete now, and some poor unfortunate
may be foolish enough to try to find, pull together, and publish it properly (electronically)
one day.<o:p></o:p></span></font></p>

else contributing to Therion.<o:p></o:p></span></font></p>
