>The original idea of Therion is that "survey" represents one survey trip. .
So it is not the best idea to manipulate with surveys.
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.
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.
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.
