Thanks for providing these additional documents. Seems like this information about exact layout of CWY and possibly RESA within (and the gold info about EMAS installment) is really only obtainable from AIPs and very hard from satellite imagery.
Which leaves two questions:
1. Are AIP (locally/globally) a valid source for adding information to OSM?
2. Can we agree on and document a scheme for mapping clearways, RESA and EMAS in OSM? In the past there was quite a mix between clearway, stopway, blast pads in OSM and some verifiable exact description is really necessary for these to work. Are you interested in working out a really comprehensive tagging scheme for all things around runway infrastructure?
