[pgrouting-dev] New version of osm2pgrouting

[Daniel Kastl]

Hi Jordan,

Thank you very much!
One of the reasons to move to Git was actually to make it easier for you
(and others) to apply changes like you sent me this summer already.

osm2pgrouting was originally written by Daniel Wendt and we offered him to
host the source code together with pgRouting.
But it doesn't belong to the library itself, that's why I made an extra
repository now on GitHub.

I think a lot of users would appreciate if osm2pgrouting would get some
improvements. Anton an I don't have much time to work on it, so we're happy
if anyone is willing to help.
You're welcome to take the lead with osm2pgrouting. Let me know your GitHub
account name. Then I can add you the list of committers.

I think it would be easiest if you could create a branch and apply you
changes to the repository yourself. I wouldn't have the time at the moment
to do this.

Daniel

> It adds the following features:
> 1. Creates and populates a way_tag table, maintaining the 1:N
> relationship between ways and tags. The use case for Ride the City is
> that sometimes we have to adjust the cost of a way based on the
> presence of two or more tags e.g. surface=* and cycleway=*, or
> highway=footway and bicycle=yes. This permits more sophisticated cost
> calculations.
>
> 2. Creates and populates a relations table and a relation_ways table.
> Ride the City also needs to be aware of relations for cost
> calculations -- mostly as they relate to local, regional and national
> bike routes. In the future, we would also want to incorporate turn
> restrictions from OSM relations. (Note that the way_id in the
> relation_ways table is actually the osm_id of the way -- not the id
> that was assigned by osm2pgrouting to the splitted ways.)
>
> 3. Adds a new command line parameter called -skipnodes. If this is
> set, the program will not load the nodes into the nodes table. This
> can be a time-consuming step and is really not crucial for routing
> (for us anyway). By default, the nodes table will still be filled as
> usual.
