Hi all
</div>
<div class="default-style">
I have a problem (again) with water depth in the map (elevated view).
</div>
<div class="default-style">
</div>
<div class="default-style">
Exporting the xvi file it looks all good and all points are at the expected depth.
<br>(as the grid in xtherion should be 1m per square)
<br>This point in the following picture is around 1.2km inside the cave and is at a water depth of 29m:
</div>
<div class="default-style">
<img class="aspect-ratio" style="max-width: 100%;" src="cid:f38f8eecd88141c28db2e1b7d993d32f@open-xchange.com" alt="">
</div>
<div class="default-style">
So counting grid squares the line is at a waterdepth of 29m (as it should be).
<br>These points are 29 squares down related to the start point at the beginning of the cave and at a depth of 0m.
</div>
<div class="default-style">
</div>
<div class="default-style">
In the map export I use a grid output for a depth line every 10m.
<br> grid-size 1000 1000 10 m
</div>
<div class="default-style">
grid-origin 0 0 100 m
<br>So the grid is with one line exactly at 0m water depth at the start of the cave:
</div>
<div class="default-style">
<img class="aspect-ratio" style="max-width: 100%;" src="cid:5c4be5074d5c4ae1ba83d273251673c1@open-xchange.com" alt="" width="258" height="372">
</div>
<div class="default-style">
</div>
<div class="default-style">
But at a point of around 1.2km inside the cave (which is the part of the xvi shown above) the cave is not at the right level:
</div>
<div class="default-style">
<img class="aspect-ratio" style="max-width: 100%;" src="cid:6c930cd19bae47f58e30532739b1a065@open-xchange.com" alt="" width="260" height="372">
</div>
<div class="default-style">
The real depth at this point is 29m and not around 35m as drawn on the map.
</div>
<div class="default-style">
</div>
<div class="default-style">
There is only one GPS point at the start of the cave and no loops (and therefore no loop closures).
<br>Why is the map morphed somehow or changed in any other way with a difference in depth over distance?
</div>
<div class="default-style">
</div>
<div class="default-style">
Does anyone have a hint what's going on and what is wrong?
</div>
<div class="default-style">
Any help is welcome.
</div>

Thanks, Torsten
