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")?;
