[OSM-talk] A source for mapping New York City never more than two days old

Since last August I work at Juno, a ride-sharing service operating in New York City only, and recently I found out we have something to share with the OpenStreetMap community. We took all our GPX traces received from drivers and published these on a tile layer under an open license. Now, instead of one wobbly track a day on a standard GPS layer, NYC mappers can enable Juno GPS layer with tens of thousands of tracks — and that is not even the greatest part.
No data on our GPS layer is older than two days. If you see a line over a closed part of a road, you can be sure a taxi driver rode over it very recently. No leftover mess from 2009, and no puzzling over which is right, a satellite imagery or a gpx track. Sure, it is only for New York, but with this geodata source, we aim to inspire employees of other companies to do the same. Our map is called street map, so why not have the best, most recent street map of all?
Of course, one cannot expect from mappers to validate the whole big city daily, so we have other internal means of map validation. But for a source, this one should serve as a definitive proof for everything street-related. I hope this might show you a glipse at a future of OSM mapping sources: when you trace not a years-old imagery, but a series of super-fresh thematic layers.
And no, we don’t plan to do any automated mapping using this layer. New York is mapped nearly perfectly: just one out of thousand taxi rides encounters some minor error, like a wrong turn restriction. I just hope other companies could provide such validation for other cities they operate in.

Have a nice mapping time,
