I'm using Open Street Map (OSM) and Open Trip Planner (OTP). To perform a multimodal logistic system I have to integrate OSM with sea routes. Specialists of ship simulation can represent sea routes using Route Exchange using RTZ-standard format.
Considering that OSM can be integrated with transit agency’s General Transit Feed Specification (GTFS), how can I convert back and forth sea routes from RTZ to GTFS?
I still don't find any tag for RTZ- they told me that it is a quite new format
