[Therion] Display Station comments on Map?

[Ben Cooper]

Hi Max,
To your original question, I achieved something similar a while ago using station comments to create an overlay for fixed stations, and another for continuations.  The pdf outputs are attached.  While the programmatic selection of stations to display would be a nice to have, it is relatively painless to do what you want manually. These were achieved using a th2 file with a dedicated scrap, as you hinted at, however, I didn't need to plot all the stations - it is sufficient just to include the station names in the scrap -stations command, making this a very viable approach.

I've included the entire th2 file below - as you can see there is a long list of station names in the scrap command, and only three points actually plotted (I can't remember why these three were plotted manually, sorry. In the fixed stations list, I had to manually plot fixed stations that were created in the cave but not yet actually tied into to the survey line - my intention was that these would be surveyed eventually, at which point I would not have to manually draw them in). It wasn't very onerous generating the th2 file - I basically searched all my the files for the stations, manipulated the search output to create the list of station names, and then copied the list into my th2 file; job done.  In fact one could easily write a script that did all of that and just output the entire th2 file.

The full Therion survey with the metapost definitions of the station points that I used is available at http://cave-registry.org.uk/svn/CheddarCatchment/UpperFlood.  Start with the thconfig files called thconfig.UF_Fixed.tp and thconfig.UF_Continuations.tp respectively.  

Here's the th2 scrap:
