[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...

Thanks Stacho

This is a useful post, and (assuming it is correct) deserves to be written
up clearly in the Therion Book and wiki.

It potentially clears up problems for which I (and others on the forum) have
been searching for a solution for years.

I may now revisit some of those old projects when I have time.

[Marco Corvi]

hi bruce and john,


i played a bit with symbol-show/hideand triedi think ti think that i think that 
hat 
symbol-show group centerline
symbol-show point cave-station
symbol-hide point station:fixed

symbol-hide group centerline
symbol-show point cave-station
symbol-show point station:fixed

and others. a bit messy, but i think that

after playing a while one can get to show only fixed (and painted) stations,
or all the station except for the fixed ones,
and other combinations ...

In my experience there are significant issues with
station visibility control.  Some previous posts here

I have been trying to just print the marked (and
painted) stations on my 
plan.
Used -
mark 1.0 1.18 1.46 fixed
mark 1.46 painted
to mark stations within the centreline in the .th file
I can show all stations with
symbol-show point cave-station
then I tried
symbol-show point station:fixed
but it didn't work, but no error occurred.
When I
symbol-show point cave-station
symbol-hide point station:fixed
it showed all points but the fixed ! so that bit is
working correctly.
 
Would also like it to show their station number, with
an option of altitude 
or position, but I may have to do this manually in the
plan rather than 
automatically from within the config file.
