<br>
Vertices vs. nodes is not a choice as one uses 'nodes' in graph
theory but also sometimes 'vertices'. Also I use them as synonym
:)<br>
<br>
Are there other alternatives?<br>
<br>
<br>

<br>
Yeah, probably :)<br>
<br>
<br>
<div>> Yes definitely!<br>

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:<br>
<a class="moz-txt-link-freetext" href="https://github.com/graphhopper/graphhopper/blob/master/docs/core/low-level-api.md">https://github.com/graphhopper/graphhopper/blob/master/docs/core/low-level-api.md</a><br>
and reference to this e.g. in the OSMReader etc<br>
<br>

what towers and pillars should be until I read some
documentation about it. So by talking about vertices at least,
it would get much clearer for.a whole bunch of geomatic related
people.</p>

[GraphHopper] What are pillar and tower Nodes?
Rename to geometry and junction nodes?<br>
</font> </div>
<div><br>
Hi all,<br>
<br>
as the naming is from 2 years ago I think it
could be time to rename<br>
'tower' nodes into 'junction' nodes and 'pillar'
nodes into 'geometry'<br>
nodes. What do you think, would this be (more)
intuitive?<br>
<br>
Below a quick documentation which I would add
otherwise to the docs.<br>
<br>
Kind Regards,<br>
Peter<br>
<br>
**<br>
From OpenStreetMap we fetch all nodes and create
the routing graph but<br>
only a minority of them are actual junctions,
which are the ones we are<br>
interested while routing. Those junction nodes I
call tower nodes which<br>
also have a graphhopper node ID associated,
going from 0 to<br>
graph.getNodes(). The helper nodes between the
junctions I call 'pillar<br>
nodes' which can be fetched via
edgeIteratorState.fetchWayGeometry<br>
