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...
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.
