And they have not been reproduced, as in copied, scanned, etc. What has been done, is taking the lat/lon for various points, such as start and end of runways, taxiways, designated apron areas, etc, and entered those points in a GPX waypoint file. This is akin to loading the waypoints into a GPS receiver, which is acceptable use, and no different from doing that as a private pilot prepping a flight, or a commercial pilot prepping the FMS system aboard the airliner. Then the gpx file has been loaded into JOSM, and lines drawn betweeen the corresponding waypoints, which then has been tagged according to the OSM tagging scheme for aeronautical content. At least for the danish data, it has been verified with SLV (Statens Luftfartsvæsen) that this procedure falls into the acceptable usage of the AIP AD charts, since widths, elevation, slope, placement of navaids, vasi, papi, tower frequencies and so on, are not entered into the DB.
