OSMnx documentation

OSMnx: retrieve, model, analyze, and visualize street networks from OpenStreetMap. OSMnx is a Python package that lets you download spatial geometries and model, project, visualize, and analyze real-world street networks from OpenStreetMap’s APIs. Users can download and model walkable, drivable, or bikeable urban networks with a single line of Python code, and then easily analyze and visualize them. You can just as easily download and work with amenities/points of interest, building footprints, elevation data, street bearings/orientations, speed/travel time, and network routing.

Citation info

If you use OSMnx in your work, please cite the journal article:

Features

OSMnx is built on top of geopandas, networkx, and matplotlib and interacts with OpenStreetMap’s APIs to:

  • Download street networks anywhere in the world with a single line of code
  • Download other infrastructure types, place boundaries, building footprints, and points of interest
  • Download by city name, polygon, bounding box, or point/address + network distance
  • Download drivable, walkable, bikeable, or all street networks
  • Download node elevations and calculate edge grades (inclines)
  • Impute missing speeds and calculate graph edge travel times
  • Simplify and correct the network’s topology to clean-up nodes and consolidate intersections
  • Fast map-matching of points, routes, or trajectories to nearest graph edges or nodes
  • Save networks to disk as shapefiles, geopackages, and GraphML
  • Save/load street network to/from a local .osm xml file
  • Conduct topological and spatial analyses to automatically calculate dozens of indicators
  • Calculate and visualize street bearings and orientations
  • Calculate and visualize shortest-path routes that minimize distance, travel time, elevation, etc
  • Visualize street network as a static map or interactive leaflet web map
  • Visualize travel distance and travel time with isoline and isochrone maps
  • Plot figure-ground diagrams of street networks and/or building footprints

Examples and demonstrations of these features are in the GitHub repo (see below). More feature development details are in the change log.

Installation

You can install OSMnx with conda:

conda config --prepend channels conda-forge
conda create -n ox --strict-channel-priority osmnx

Alternatively, you can run OSMnx + Jupyter directly from its official docker container, or you can install OSMnx via pip if you already have all of its dependencies installed on your system.

Examples

For code and usage examples/demos, see the examples GitHub repo.

Support

If you’ve discovered a bug in OSMnx, please open an issue at the OSMnx GitHub repo documenting what is broken in the package. Alternatively, if you have a usage question, please ask it on StackOverflow.
