[osmosis-dev] Osmosis and Osmium-enhanced PBF files with way node locations

[Brett Henderson]

Hi Jon,

It sounds like a great initiative.  Linking ways to locations efficiently
is perhaps the greatest challenge of working with OSM data, and the one
I've spent more time on than most.  Including that information in the raw
data sets would be a huge boon for downstream consumers.

As you may have noticed Osmosis development is fairly quiet these days.
I'm not able to spend much time on it, and it doesn't see many other
contributions.  Unfortunately this means you'll probably be on your own.
I'll do my best to answer any questions, but am unlikely to be able to help
directly.

I'm curious about whether it's worth adding to Osmosis.  Are there many use
cases that other tools like Osmium don't cover?  If there are that's great,
I'm a bit out of touch.

Cheers,
Brett
