What Hacker News says?
> unless you already have some details such as the lat/Lon of dropoff and pickup and time of the stops. These are literally columns in the data set. To quote the original post: Each file has about 14 million rows, and each row contains medallion, hack license, vendor id, rate code, store and forward flag, pickup date/time dropoff date/time, passenger count, trip time in seconds, trip distance, and latitude/longitude…

HN discussionFWIW: - 2013 data as FOILed by Chris Whong http://chriswhong.com/open-data/foil_nyc_taxi/ - 2008 to 2013 data as FOILed by me, on BigQuery https://bigquery.cloud.google.com/table/alien-climber-851:ny... ...note that after Whong's request, the TLC redacted the medallion numbers, making it virtually impossible to analyze trips by cabbie.

HN discussionThe data is from http://chriswhong.com/open-data/foil_nyc_taxi/ -- I pulled 10k random pickups from each day/time for the heatmaps. I used http://leafletjs.com/ and https://github.com/Leaflet/Leaflet.heat for the visualization.
