Is this course still open? From (what I believe to be) recent imagery, it seems like fairways have been converted to a tree farm. And from what I can tell based on some searching, it seems like it last operated in 2020 and the clubhouse is now an event venue. If that's correct, and if it's unlikely to be converted back, it would be good to add the abandoned prefix so that consumers of the data don't see it as an active course. See https://help.openstreetmap.org/questions/62156/how-to-map-a-defunct-golf-course/

👍 Fixed. I seem to remember having trouble getting that to work with iD in the past, but seems to work fine now. I'll do it from now on. Thanks!

👍👍 Thanks for all that you do!

To summarize the post, the approach would be to add a golf:course:name tag to each golf=hole way in order to designate which course it belongs to. So in this case, it could be Der A-Kurs
and Der A-Kurs based on the naming from the course website you linked.

@highflyer74 The golf=hole wiki says that the ref=* should be the "number of the hole". A1 & B1 are alphanumeric strings, not numbers. At this course, it seems the reason for the A & B prefixes is to differentiate the A and B 9-hole courses. Unfortunately, the OSM golf spec doesn't really account for multiple courses within a single boundary. It is a problem we've come across many times, and another mapper referred us to this thread where a solution was proposed: https://help.openstreetmap.org/questions/75934/golf-course-how-to-differentiate-between-two-18-hole-courses-at-one-club We have adopted that approach, as have some other golf course mappers.

This has been updated to reflect the correct golf course and address. Thank you for raising,

The address has been corrected. The person that was helping with this is no longer on the project, and all of their previous work will be reviewed in the coming weeks. I share your commitment to quality data, and thank you again for raising this.
