is also with the same geometry

Note that while it was published in official sources it was mapped with 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 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.

>> 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.

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