Great job! This is very useful. The search by city, state doesn't seem to work. If you enter something like "los angeles, ca" it returns no results. zip code search works fine.

Only state and zip currently. City names not yet supported (its another 3000ish pages)

Golf courses in USA use half a trillion gallons of fresh water annually. All data centers use less than 0.2 (of which only less than 0.02 is used for cooling the servers, the rest is just electricity generation, which can and should be replaced with solar). There's no replacement for water usage for golf courses and even half a trillion number is after recent 30% reduction of usage from what it was before.

Good thing water replaces itself!

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.

course details are not that great on OSM. typically just some polygons labeled 'golf course' and maybe a number of holes

Possible bug: Went scrolling way East on the map for kicks and was surprised to find 14 courses on Guam, but also that the data don't repopulate as you make it back around the globe a second time. This seems to happen in both directions—eg Guam doesn't populate at all if you scroll West.

looking into it thanks!

Fixed and deployed! Markers only existed on the primary copy of the world, if you ever scrolled passed it would have nuked all the pins. Thanks for the report!

So, I started https://golfcourse.wiki in 2020, and I see courses that basically only I’ve mapped. It’s cool, I want it to be public, if you want to work together, do reach out. I would also say what you are doing is almost certainly opening you up to liability if you are just scraping other sites and republishing their data. One paper town that you published and you might have a lawsuit on your hands. https://en.wiki…

There's already one club I can see on there that doesn't actually exist. Is a running gag in the area where I grew up, and made it on this list somehow. So that's weird.

please report it on the site!

Earlier quoted context omitted.

In the USA they are overwhelmingly public and are desperate for customers. The handful of private ones near me are also desperate for new members, and several country clubs have ended up closing. Considering some of the golf courses that have closed around me ended up being converted into Amazon distribution facilities, I am not terribly excited about the idea of more golf courses closing.

In the USA as elsewhere golf courses are incredible wastes of water and false green spaces that would function better as green spaces were they actually parks open to the public they serve the wealthy. What is different is that in the US there is very little real (operational) worry about waste of water (or other resources) - at least compared to other places - and there is lots of space compared to other places.

Where I live the municipal courses are actually a part of our water retention and drainage systems that are provided at cost (or discounted cost, sometimes free) to members of the community.

Basically we found a good way to create green spaces for recreation out of flood plains and drainage ditches. During heavy rain they provide important buffers that protect the nearby homes from flooding, and reduce the urban heat sink effect.

That's not true everywhere but keep it in mind before making sweeping statements about golf courses. Some people like golf. It's fine if you don't.

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.

yeah i am pulling from OSM. I can probably draw those polygons. It;s been an OK source for number of holes etc but I need to cross reference to get other detailed info

I was thinking image analysis from satellite images, but of course start with what’s annotated (OSM)
