osm4routing2
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.
Build
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.
Importing in a database
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).
Using as a library
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")?;
If you want only specific tags, use required
; it accepts "*" if any value is accepted; if multiple conditions are given, it will accept any way that matches at least one of the values.
let (nodes, edges) = osm4routing::Reader::new().require("railway", "rail").read("some_data.osm.pbf")?;
If you need to read some tags, pass them to the reader
:
let (nodes, edges) = osm4routing::Reader::new().read_tag("highway").read("some_data.osm.pbf")?;
If want to contract edges that come from different OpenStreetMap ways, but where there is no intersection (that can happen when the tags change, e.g. a tunnel):
let (nodes, edges) = osm4routing::Reader::new().merge_ways().read("some_data.osm.pbf")?;
