I have been getting into Zusi recently, and the editor is of special interest to me. I have been working through the tutorial but there are still some questions I do not have answer to (some things may have been lost in machine translation ^^)
1 - The route "profile" is saved as .st2 which is basically an XML. I can easily understand that straights, clothoids, arcs... are listed with start and end coordinates (and more if applicable e.g. radius or superelevation). But taking the attached from the tutorial files as an example:
Code: Alles auswählen
<Gerade st2Typ="1" ProfilName="Wenholthausen" spTrass="16.66667" Oberbau="Stahl K-Oberbau">
<PunktWinkel X="-29.30414" Y="43.82437" W="-0.9446389" />
<PunktWinkel X="187.3776" Y="-255.7719" W="2.196954" />
</Gerade>
For a route I want to build, I have access to basically all the info used in the .st2 but as a csv and with a different formatting that I could easily convert, so long as I understand the Zusi file format well enough.
2 - Assuming I have a partly-made st2 file with tracks laid in the right place/coordinates but no height data. Is it possible to open the st2 in Gleisplaneditor, then apply DEM height profile (as per chapter 3.2.2.4 of Doku)?
I tried this with a st3 file created by transdem, but got a "point {x=... y=....} cannot be aligned with profile" error. (I tried importing a georef bitmap, and creating the profiles before importing the routes but with no luck. I am guessing this has to do with using a st3 and not a st2 as input...? But the height profile assignment is still reflected, in terms of name and color.)
3 - On this topic it seems like the way to build routes is to split them in modules.
What is the typical size/track length for one module? I assume you would split off major stations in separate modules, but how many km would a countryside high speed line module be for example?
4- What formulae/method does the editor use for calculating clothoids/transition curves? There are some variations depending on the country, the principle is the same but the numbers vary to some extent. I know the methodology using the american methods but their units are messed up ^^
5- In the st2 file, the straights/curves/clothoids are listed in a certain order. Does this order matter at all ? i.e. Is it possible to list all the straights, all the curves, all the clothoids grouped by type rather than in the actual order they would appear if you travel on the line?
Sorry, this may be a lot of questions... And others may still come . But the options are very deep and I am enjoying it.
Thank you in advance for your help
