> 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 presume they simplified the geometry in polygon with X ammount of vertices) or they have used other data. Compared the data from 10 EU countries and they all match OSM.

Without a doubt its from OSM, the coordinates of the vertices matches OSM perfectly. The names are also the same...
