Thank you all for your input!
> in GI science we speak of 'vertices' for pillars and just 'nodes' or 'junctions' for that what you know as tower nodes. Vertices vs. nodes is not a choice as one uses 'nodes' in graph theory but also sometimes 'vertices'. Also I use them as synonym :) Are there other alternatives? > Without looking at the documentation, I wouldn't know what "junction" and "geometry" nodes are either. Yeah, probably :) > Yes definitely! > I'd say that junction and geometry is more immediately descriptive and intuitive, > though the meaning of tower/pillar isn't really obscure. It would seem a small but worthwhile improvement in comprehension/usability Okay, so I'll do the change (after waiting a week for vetos or other suggestions) and properly document this stuff in the low level API: https://github.com/graphhopper/graphhopper/blob/master/docs/core/low-level-api.md and reference to this e.g. in the OSMReader etc Regards, Peter On 01.12.2014 20:44, Jürgen Zornig wrote: > > Well, in GI science we speak of 'vertices' for pillars and just > 'nodes' or 'junctions' for that what you know as tower nodes.
