In Australia ... it does have commercial & military airports ... but no
small airports
military areas
prisons
national parks (yes some of these these are illegal unless you get 
special permission)


In short .. does not do a good job if you wanted real no fly information.

different geometry

After more investigation noticed that the military facilities on OSM 
that don't have name, also don't have a name on DJI also. If you search 
on OSM the name of the facility based on DJI info they match... wonder why
Few users reporting that the geometry don't match in some countries (i

I don't see other data than airports in Taiwan. As I mentioned on the
initial, I'm talking about the military facilities and prisons, not
airports. China also don't have military facilities on their map, being a
Chinese company they probably filtered it.

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

[Ilya Zverev]

Hi folks,

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.

See the announcement in the diary: 
https://www.openstreetmap.org/user/Zverik/diary/47986 

And explore our GPS traces yourself: https://gps-tile.junolab.net/ 


Have a nice mapping time,
Ilya___
