<font face="Arial">Was curious where DJI managed to get a worldwide
DB of polygons of military facilities and points of prisons,
triple checked with a couple of other users of OSM at Telegram and
with polygons i added seven years ago. Without a doubt its from
OSM, the coordinates of the vertices matches OSM perfectly. The
names are also the same...<br>
<br>
Check yourself, head to <a href="https://www.dji.com/pt/flysafe/geo-map" target="_blank">https://www.dji.com/pt/flysafe/geo-map</a>
select your country, zoom in and check the data. Airports
restriction areas seems not to be OSM data, but from other source.
<br>
Share your examples if you will.<br>

Again, sadly no attribution... tried to request via Twitter <a href="https://twitter.com/iamnunocaldeira/status/1105897635796447235" target="_blank">https://twitter.com/iamnunocaldeira/status/1105897635796447235</a>
.... silent as in moon why would they reply to a contributor blah.
The Pandora box has been opened with exceptions about the
attribution, if other don't attribute, why would they?<br>
