Data requirements

In order to conduct transport routing and accessibility analysis using the {r5r} package, you will need a few input data sets:

• A road network from OpenStreetMap (OSM) in .pbf format (mandatory).
• A public transport feed inGTFS.zip format (optional).
• A raster file with Digital Elevation Model data in .tif format (optional).
• Some data on the spatial distribution of population and/or activities such as employment, schools, health care facilities.

The data sets we’ll use in this workshop are provided with the code exercises. If you would like to find similar data for you other regions in the world, here are a few data sources. See also slides below.

• Street network (mandatory):
  • {osmextract}, R package;
  • Geofabrik, website;
  • HOT Export Tool, website;
  • BBBike Extract Service, website.
  • Protomaps website
• Public transport network (optional):
  • {tidytransit}, R package;
  • Transitland, website;
  • Mobility Database website
• Topography (optional):
  • {elevatr}, R package;
  • Nasa’s SRTMGL1, website.
