[Therion] Surface profile in elevation maps

[Bruce]

Steve

I'll add the gpsvisualizer to the Therion wiki, as it looks like a good way
to get a smoothed ground profile over a cave centreline.  Just so I'm clear,
did you just upload your therion generated kml file here?

 



 

If you want to make a terrain model, then TerrainTool is the way to go

Therions default pdf outputs

 

>I do have a bit of a problem in exporting to pdf, and this may be me 

missing something more fundamental in how survey/maps are structured and 

therion builds up the plot :

 

>When I just plot centreline data, I can see cave centreline and the new 

ground surface centreline for the complete cave length. 

 

 If you do not explicitly select a survey or map (ie you only have source
data) and the source does not reference any scraps, then default the entire
centreline is plotted.  As you observed above.

 

 

>When I include a single cave scrap, I no longer see any centreline data
outside this 

single scrap. Is there a way to over-ride this behaviour or alternatively
how should I structure my survey/map objects to avoid this?

 

 And as soon as the source references scraps, then only the scraps (and all
of them) are exported.

To gain control over what is output, you have to select surveys or maps to
be exported.  The easiest way is to select is to use the Xtherion compiler
window.  You can only do this after you have successfully compiled.  Open
the Surveys or Maps window on the righthand side, and double-click the
survey or map you want to select.  Xtherion adds the select statement to
your thconfig file.



A little more explanation in the thconfig templates on
http://therion.speleo.sk/wiki/doku.php/templates and in the Therion Book pg
56.
