[Therion] Marked stations

[Bruce]

Related to the issue of the inclusion or exclusion of particular station
symbols in pdf outputs, there is a long standing behaviour that has been
frustrating me.

 

I would like to create a pdf that has;

-cave passage outlines, but no cave survey network information, and

-fixed surface points with labels, and no surface drawings and no other
surface survey network information.

 

I have used these statements in a layout;

  symbol-hide group all  

  symbol-show point station

  

  symbol-hide group cave-centreline    

  symbol-hide point cave-station   

  

  symbol-show group surface-centreline

  symbol-show point surface-station 

  

  symbol-show point flag:entrance 

  symbol-show point flag:sink        

  symbol-show point flag:spring      

  symbol-show point flag:doline      

  symbol-show point flag:dig 

  symbol-show point flag:continuation  

 

They more or less describe what I want (except for the surface centerline
statement).

 

I have used two source files.

'One' references cave data that has lots of drawings, plus a small amount of
surface data and surface drawing.

 

'Two' references surface data (and a few cave stations) that is almost
exclusively made up of fixed points (gps data) and has no drawings.

 

If I reference 'one' only then I get the following image.  Pretty much what
I wanted, except for the surface survey stations (notice that I have
'symbol-show group surface-centreline' above, but the surface centerline is
not plotted).

 



If I reference 'two', then I also get pretty much what I want, except that
some of the points that are displayed are cave-stations.



The above two screenshots from pdfs are created with the same dataset and
cover approximately the same area and are at approximately the same scale.

 

So, apart from the minor exceptions mentioned, I would like to create a pdf
map that is a superposition of the two screenshots.

 

When I reference both sources 'one' and 'two', in the same thconfig file,
the project compiles and outputs are produced.  The problem is that the pdf
output produced looks identical to 'one' above.  Ie the source that includes
mainly surface data is not included in the pdf.

 

For this example other types of output such as .lox and .3d are created
correctly.

 

Would this be a bug? Or something I am doing wrong?

As Marco already mentioned, it can be done after playing a little bit with
symbol show/hide.

Well, I needed to run therion in debugger to see, what is going on.

 

The problem is, that there are multiple "attributes" and therion does
support only hide show for single symbol type. Therefore, specification is
tricky. But in your case, this is what you can use:

 

symbol-hide group centerline

 

 symbol-show point cave-station

 

 symbol-show point station:painted 

 

symbol-show point station:fixed





First line hides all centerline symbols from everywhere (stations and
shots).

 

Second tells therion, that you want to show stations in the cave. But in
fact - point cave-station itself does not show any symbol. It only
specifies, that stations in the cave should be shown.

 

Therefore 3. and 4. lines are needed to specify, that you want painted and
fixed stations to be shown.

 

 

In fact, if you use symbol-hide group centerline, and want to show some
station afterwards, you need to specify explicitely both, whether you want
to show stations in cave or on surface and which kind of stations you want
to show. You can use also symbol-show point station to show all kinds of
stations.

 

And now I am not sure, whether I understand my self ;)

 

But at least, this configuration seems to work on my data sample.

It would be great to have some kind of query language, show/hide/color
symbols...
