This project is a rewrite in rust from https://github.com/Tristramg/osm4routing
It converts an OpenStreetMap file (in the .pbf format) into a CSV file.
Get a rust distribution with cargo: https://www.rust-lang.org/en-US/downloads.html
Run cargo install osm4routing
You can now use osm4routing <some_osmfile.pbf> to generate the nodes.csv and edges.csv that represent the road network.
If you prefer running the application from the sources, and not installing it, you run
cargo run --release -- <path_to_your_osmfile.pbf>
The identifiers for nodes and edges are from OpenStreetMap.
The id property of an edge is unique, while the osm_id can be duplicated.
If you prefer having the files in database, you can run the very basic import_postgres.sh script.
It supposes that a database osm4routing exists (otherwise modify it to your needs).
In order to use osm4routing as a library, add osm4routing = "*" in your Cargo.toml file in the [dependencies] section.
Use it:
let (nodes, edges) = osm4routing::read("some_data.osm.pbf")?;
If you wand to reject certain edges based on their tag, use the Reader (it also accepts "*" to reject every value):
let (nodes, edges) = osm4routing::Reader::new().reject("area", "yes").read("some_data.osm.pbf")?;
