<p class=MsoNormal><font size=3 color=navy face="Times New Roman"><span

Therion is that "survey" represents one survey trip. <font

idea to manipulate with surveys. <o:p></o:p></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I agree Martin, one survey file, one trip.
However we just did a survey of three small multi-entrance caves and overland
surveys over a couple of days. In hindsight we were a bit messy in
practice as we surveyed into one cave and out of another entrance and into
another cave, then back out to the first cave etc etc. <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'><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'>What I found was that Therion could not (or
I could not get Therion to) adequately resolve the statistics for the caves
individually until I split some of those surveys into two or three. It
also would not separate surface survey statistics from cave statistics (but I
think that is a bug). Statistics are resolved correctly for maps but not
for survey-list.<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'><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'>So as a last resort I cut the survey trips
into multiple surveys/files. If I had drawn the scraps before doing this
I would have had a difficult job patching it all back together. An
unusual situation perhaps, but one where manipulation of the survey files was
able to lay a better foundation on which to build scraps and maps.<o:p></o:p></span></font></p>
