I was going to provide some potential counter examples, but Grant's time frame may be involved. My information suggestions the OSM data was captured before Feb 2018.
North East England, UK. This TA Centre is shown on DJI: https://www.openstreetmap.org/way/41586101 This TA Centre is not shown on DJI: https://www.openstreetmap.org/way/77034151/history (landuse=military tag added Feb 2018) A good supporting example is that Ouston Airfield is mapped in multiple landuse=military parts for the runway. Really it should be fixed in OSM as one area, and the runways tagged differently. https://www.openstreetmap.org/#map=15/55.0223/-1.8692&layers=N I do hope you get a reply from DJI. If not then you should forward on the details to the DWG. >From a safe zone, Gregory.
