Hello Thomas,
I'm not over the moon with the present visualisation model either. I'm
however convinced that visualisation is important for two reasons:
1. a visual representation of the infrastructure helps both the modeller
and the user. This is highly useful for gaining acceptance of RailML.
RailML can go the GIS-way. Lack of visualisation makes for a very opaque
tool.
2. often, multiple plans, maps, schemas are linked with an infrastructure.
E.g. there's a track plan of a station for maintenance purpose and another
schema of the same station for dispatching. Both refer to the very same
infrastructure. It is helpful to associate more than one set of
coordinates with infrastructure. So, in my opinion, it is great if we can
link an object with several coordinates. This actually reduces the
probability there are multiple discordant plans floating around.
concluding - visualisation is important but the XSD needs some
improvement.
Yours,
Bob Janssen
