[GraphHopper] Improve geocoding
Open, HighPublic
Actions

Description

Actual

Suggestions for the autocomplete menu in To, From, or Via fields do not always show relevant results. Some localities are far away.

Expected

Suggestions include places close to user.

Practically, we can improve with any of:

  • Use a location bias lat/lng. Currently, GraphHopper UI does only use the other input fields as location bias. Notably, there is initially no location bias with empty From and To fields. We could use the user home lat/lng (as defined in user profile from his postal code).
  • Give more importance to the location bias. Currently not an option in GraphHopper geocoding requests.
  • Use Mapbox JavaScript API for geocoding, instead of GraphHopper one.
  • Use Google Maps JavaScript API for geocoding, instead of GraphHopper one. Note that Google Terms of Use would require us to use Google Maps tiles to display results, instead of currently Mapbox.

As discussed during meeting,

  1. we should start using the ZIP of the user
  2. Use the From to bias the To (radius 200 km)
  3. If the map is moved, the calculate the centre and use this for bias.
