OpenStreetMapX.jl

• Package for spatial analysis, simulation and visualization of Open Street Map data
• The plotting functionality is provided via a separate package OpenStreetMapXPlot.jl
• OSM file manipulation, point-of-interest (POI) extraction functionality and support for walkability indexes is provided by a package OSMToolset.jl

The goal of this package is to provide a backbone for multi-agent modelling and simulation of cities.

The package can parse *.osm and *.pbf (contributed by @blegat) files and generate a Graphs.jl representation along the metadata.

Documentation

• STABLE — documentation of the most recently tagged version.
• DEV — documentation of the development version.
• TUTORIAL — A simple tutorial showing routing simulation with OpenStreetMapX along with integration with folium via PyCall.jl
• JuliaCon 2020 TUTORIAL — See the tutorial that has been presented during JuliaCon2020! A research application of this tutorial can be found in our paper On Broadcasting Time in the Model of Travelling Agents.
• JuliaCon 2021 TUTORIAL — NEW See the tutorial that has been presented during JuliaCon2021!

Installation

The current version uses at least Julia 1.6.

using Pkg; Pkg.add("OpenStreetMapX")

In order to plot the maps we recommend two tools:

• rendering the maps yourself with PyPlot or Plots.jl with backend - use the OpenStreetMapXPlot.jl package
• extracting points-of-interests (POIs) from maps (such as restaurants, parks, schools, hospitals, grocery stores) - use the OSMToolset.jl package
• rendering the maps with Leaflet.jl - use the Python folium package (examples can be found in the tutorial and the manual)

In order to install all plotting backends please run the commands below:

using Pkg
Pkg.add(["Plots", "OpenStreetMapXPlot", "CondaPkg"])
using CondaPkg
CondaPkg.add_channel("conda-forge")
CondaPkg.add("folium")

Usage

using OpenStreetMapX
filename = OpenStreetMapX.sample_map_path()
map_data = get_map_data(filename);

println("The map contains $(length(map_data.nodes)) nodes")

The picture above has been generated with folium - for source code see the samples directory for a more complete example and have a look at OpenStreetMapXPlot.jl for a route plotting.

Obtaining map data

The simplest way to get the map data is to go to the Open Street Map project web page.

In order to obtain the *.osm file follow the steps below:

1. Got to the area of your interest at https://www.openstreetmap.org/
2. Click the "Export" button at the top of the page
3. Click "Manually select a different area" to select the area of your interest
4. Press the "Export" button on the left. Note that sometimes the Export link does not work - in this case click one of the links below the Export button (for example the Overpass API link)

Acknowledgments

<sup>This code is a major re-write of project - available at https://github.com/tedsteiner/OpenStreetMap.jl .

Compared to the original package major changes include among many others:

• New Graphs.jl is used for map data storage
• Several changes with routing algorithm (currently finding a route in a 1 million people city takes around 150ms)
• Added support for using Google Maps API for routing
• Data structure adjustment to make the library more suitable to run simulations of cities.
• Plots.jl with GR is used as backend for map vizualization (via a separate package OpenStreetMapXPlot.jl)
