This OSM-derived catalog is separate from sites-sk-cz.json and personal browser settings. Derived names use nearby OSM settlements. Names are not official where generatedName is true. Coordinates are not confirmed pilot locations; all imported sites start with a 360° assumption. Nearby source objects are preserved independently. Excluded: negative tags, taxiways/aprons and helicopter-only sites. Snapshot 2026-10-14.
