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

[Locke, Jonathan]

Hello All!


We were discussing today on the #dev Slack channel the idea of extending Osmosis to handle enhanced PBF files created by Osmium that have location information for each WayNode. This has the potential to eliminate the need for giant node-to-location maps consuming tens of GB of RAM when processing planetary PBF files.


I'd like to see this happen as OSM data keeps growing exponentially and I'd be more than happy to help out with the changes to Osmosis if that would be useful. Once we have an OsmosisReader than can handle these enhanced PBF files (and, obviously, older PBF files as well), it would be nice to take the next step and have them published by the OSM project. Although we'd prefer the enhanced data be centralized so everyone has easy access to it, we could also do this part if resources to do it are limited.


Best,


     Jon
