This is supercool. But I have a tangential question. I see projects like this built on top of OSM for different use cases. Does this data gets contributed back to OSM. A lot of them seems hobby projects, so it's hard to maintain long term, but the data is quite useful and could be used beyond the lifetime of these projects if they can be contributed back to OSM somehow.

OSM probably has the best data on golf courses because for many courses, people have mapped each 'golf=hole' as a way, and mapped other golf course features such as 'golf=bunker', 'golf=green', etc.

OSM knows of almost 40k golf courses around the world.[2] This compares to 38k golf courses known to the R&A Golf Around the World Fourth Edition (2021) report and 37.6k courses listed in the NGF course database as of July 2024. It's likely OSM knows of 99.99..% of all active golf courses and also still retains tags for closed/unused golf courses too. So if OSM were to be inaccurate, it'd likely be inaccurate for whether a golf course is open or closed, rather than OSM not knowing about a golf course existing.

I wonder whether an OSM tile server / custom style sheet for golfers would be easiest and most useful/comprehensive way to keep track of golf courses?

It would be interesting to map this to parkinson's data.

Are you suggesting a causal link between Parkinson's Disease and golf course locations? Or is "Parkinson's" a golf term??

Some pesticides may be linked to Parkinson’s Disease cases

That is what OP was trying to say I assume

As I recall, OSM already tends to have many golf courses mapped in extreme detail, because there’s a game that lets you play OSM golf courses on your golf simulator.

This sometimes leads to conflict between the game’s passionate users and OSM, when they map every road around a golf course as a cart path, because that’s the only thing the game imports.

Nice! Someone shared thAT wiki with me recently on reddit. I had not been aware of it before. Great stuff! I'm not a lawyer but my stack is clean. My base layer is OSM, which is licensed for exactly this stuff (and attributed). On top of that I used golfcourseapi.com which i also recommend (affordable, and fairly reliable so far, but not always current). Then community notes etc. I cross reference against other sourc…

Sounds good, and it would make sense that OSM and I have some crossover at this point. Now that I've had more time, I can see that the extremely obscure courses are not in your dataset (Like Ulukhaktok GC: https://golfcourse.wiki/course/ulukhaktok_golf_course-ulukha... ). Unfortunately, I didn't have a lot of time to look through your site when I saw this post, so I’m sorry about that. Just so we're clear, I'm effect…

Sounds good. And yeah ideally i can link to a course's direct booking links but they are often harder to find.

Do you plan to contribute the data back into OSM? That would be the nice way to go to share with the community and allow you to have better data in the future with less maintenance work.

Not yet but i'd like to port it back somehow eventually. I've definitely named a lot of their unnamed courses on OSM

I'd like to to the same with my data (allow a download of all the course pages) eventually. I'm only publishing facts at the moment but would love to support other features (local ratings, reviews, etc)
