[Open-transport] Hafas Raw Data Format to GTFS conversion (Zürich)

[Stefan Wehrmeyer]

Hi Thomas, Brian, list,

the format is not binary, it's a latin1 fixed column text format. It has "binary" portions as ascii hex strings. The specs are pretty detailed (read long) but seem to cover everything.

Be aware that the names of the files in Zürich dataset differ from the spec I linked to below.
The important file is ZUGDAT (called FPLAN in the specs).

You can find the data here:
https://dl.dropboxusercontent.com/u/3250791/5_TU_CH_OeV_Sammlung_CH_2013_130503_0459.zip
(~80 MB)

If one of you decides to start building a conversion tool I would encourage you to build it as Open Source and in the open because I'd love to test and help out!

Cheers
Stefan
