Show HN: I mapped every US golf course – 16k+ courses, free, no signup

https://golfcoursebrowser.com/
42•rickmf•1h ago
I got tired of Googling basic course info, so I made a free directory of every US course

Google filters for golf course results are terrible so I built a better way to browse courses using OSM as the backbone.... https://golfcoursebrowser.com/

It's a work in progress and mostly US for now, but I want to expand to the rest of North America, the EU, and the rest of the world ASAP.

It's free, no ads, no login, no bs. If you spot anything wrong (bad info, a missing course, wrong scorecard), you can flag it right on the course page. I actually read those and fix them.

Still a lot of missing info, but I'm filling out more and more each day. The goal is the most complete, and current golf course directory in the world, verified and maintained by actual golfers. I think is attainable in the next few months. The base layer is OpenStreetMap, cross-checked against course websites and enriched with scorecards, USGA rating/slope, and public/private status. User corrections from golfers who know their home course have beaten every commercial data source we check against.

I was going to say you were missing this one but I'm not sure if it's still open after the county purchased it.

Now add mini golf courses.

great! have you seen https://openskimap.org/ and https://openskistats.org/... maybe change name to open golf map?

Nice job! When I zoom in on Google earth you can easily see if it’s actually a golf course or not, would been interesting to use this to draw up the areas with polygons and some more details.

Then you could start providing a lot more details about each one automatically.
