Make a geojson file out of the app dump for CitiBike locations

create_citibike_geojson.rb

# citibike stations: http://appservices.citibikenyc.com/v1/station/list
# Save this json file as "citibikestations.json"
# The result is a file called "citibikestations.geojson," which Qgis will read with no trouble. Leaflet too.
require 'json'

      "status" => p["status"],
