Convert google maps routes to geojson coordinates for use in Mapbox, etc

gmaps2geojson

Super simple python utility for getting GeoJSON from Google Maps routes.

Setup

Written using Python 3.6. Install requirements with pip install -r gmaps2geojson/requirements.txt.

Get an API key for the Google Maps Directions API. Set this as an environment variable.

export GMAPS_KEY='YOUR API KEY HERE'

Usage

>>> import gmaps2geojson
>>> writer = gmaps2geojson.Writer()
>>> directions1 = writer.query("2131 7th Ave, Seattle, WA 98121", "900 Poplar Pl S, Seattle, WA 98144")
>>> directions2 = writer.query("900 Poplar Pl S, Seattle, WA 98144", "219 Broadway E, Seattle, WA 98102")
>>> directions2
*Will output all [long,lat] coordinates of geojson line
>>> writer.save("example.geojson")

or combine all queries into an array and use query_array

>>> import gmaps2geojson
>>> writer = gmaps2geojson.Writer()
>>> directions = writer.query_array([
      ["2131 7th Ave, Seattle, WA 98121", "900 Poplar Pl S, Seattle, WA 98144"],
      ["900 Poplar Pl S, Seattle, WA 98144", "219 Broadway E, Seattle, WA 98102"]
    ])
>>> directions
*Will output all [long,lat] coordinates of geojson line
>>> writer.save("example.geojson")

• query(src, dest, custom_label=None): Use the query function to get a list of coordinates -- derived from the first result on Google Maps between the provided source and destination. Returns list of (longitude, latitude) coordinates
• query_array(src_dest_array, custom_label=None): Same as the query function, only this accepts an array of [src, dest] string locations. Returns a list of (longitude, latitude) coordinates connecting each location. Passing an array of [["San Carlos, Antioquia, Colombia", "Villavicencio, Colombia"],["Villavicencio, Colombia","Cali, Colombia"]] will calculate the coordinates connecting San Carlos to Villavicencio to Cali. Write those coordinates to a file using...
• write(filename): Outputs geojson of all queried routes. All routes have a name property in the format of <src> to <dest> unless a custom_label was specified when querying.
