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...
Interesting in that the sites near me have used the boundary of the wall / fence instead of the surrounding and larger area identified with "amenity=prison".
