Hi all,<br>
<br>
Hope that someone will be able to help me during this summer
vacation, knowing that it's the perfect timing for exploring and
surveying caves (but also to do the synthesis of past surveys)...<br>
<br>
So, I'm working on an extended elevation map of a small but complex
cave in the South of France (+/- 1500m length & +20/-40m high).
Survey was done with a DistoX2 and Auriga (13 surveys were done if I
remember but I haven't attached all of these). Most of the cave is
made of boulders (énorme éboulis), probably from tectonic origin; so
there are plenty of loops (it's a nightmare) and at least 5 or 6
levels. I haven't been working yet on the plan map but I guess it's
not going to be a piece of cake (from a loop point of view).
Sketches were done by hand to help me during the synthesis. I
created an XVI file and I use it as background image.<br>
<br>
I'm working on PC an my therion version is :<br>
<img src="cid:part1.01060000.04060402@laposte.net" alt=""><br>
<br>
So my problem is the following (screenshots below): station 3.2 is
unique but there are at least 2 side passages going to different
locations of the caves (see screenshots 1a & 1b). During the
survey, Auriga was displaying a unique 3.2 station and different
paths (one going to 5.1, then 5.2 and the other one going to 3.11
then 3.16 and so on; see screenshot 3 below). But when exported from
Auriga into a Therion format and then openned in Therion, I get two
3.2 shifted stations (scale is 1m x 1m), one for each path, as seen
in the screenshot 2a.<br>

<br>
The 2 stations were surveyed at different times (but from the same
station/point as stated earlier).<br>
<br>
There are other stations with the same 'shift' problem (I'm only at
the begining of the synthesis process). For instance, station 5.2
-which comes just after 3.2- is also shifted as seen on the screen
shot #2b.<br>
<br>
Is there something wrong I did ? Something I should do instead? <br>
<br>
I've tried to "equate" stations 3.2 and 5.2 (I renamed them before
inserting the equate in the survey: first 3.2 in survey #1 is kept
as 3.2 but second 3.2 in survey #2 was renamed 3.2bis; same for
5.2). Station was shifted/merged of course but I was not able to
shift my second 3.2 branch to the 1st one..<br>
<br>
I have checked the very usefull "Therion by example", by Marco
Corvi, in the <i>4.4.2 Loops in extended elevation</i> paragraph
but I was not able to make it...<br>
<br>
Am I clear enough in my explanations? <br>
<br>

<br>
Why does Auriga is correctly displaying this sort of survey (see
screenshot #3 below) and not Therion, by default I mean ? I'm not
criticising, of course, it's just a remark from a beginner.<br>
-from station 3.2, there are 3 different paths going to 3.11, 5.1
and 3.3<br>
-from station 5.2, there are at least 2 different paths going to
5.47 & 5.3 (there are probably other ways I haven't check)<br>

<br>
Would someone be kind enough to explain me how to deal with it,
please? then i should be able to solve most of the others shift
problems I'll face during this synthesis...<br>
<br>
