Official aviation overlays come from ATNS aeronautical publications. Imported overlays come from files you provide.
Trust hierarchy
- Official ATNS airspace and aerodrome data — authoritative for aviation structure;
- Weather models — planning estimates;
- Imported KML/KMZ — reference only unless you verified the source.
Risk assessment
Aviation risk uses official data inputs. Imported layers are visual aids and do not override official airspace detection.
