Problematic mapping/golf
Golf simulator game players come to OpenStreetMap to improve their game. They may not follow editing norms or respond to messages. Please contact the Data Working Group if problematic golf mapping is identified.
The Golf Club Games
Most deliberate additions of incorrect data are for the purpose of use with the project TGC-Designer-Tools. TGC-Designer-Tools is a golf course creation utility that uses OSM and LIDAR data to create 3D models of golf courses for video games. The compatible video games are The Golf Club 2019 and the PGA Tour 2K series, developed by HB Studios. The TGC-Designer-Tools utility is a third-party application with no affiliation to the HB Studios video games. TGC-Designer-Tools imports OSM data for the keys water, waterway, highway, natural, building, and golf.[1]
How-to YouTube
There are instructions for course mapping on YouTube that offer problematic suggestions such as:
- Change all roads to cart_path to prevent import: https://youtu.be/WYa4ODgo-Bc?t=1970
- All buildings should be tagged building=office. Instead, buildings should be tagged with values according to Key:building
- golf=fairway should overlap with golf=green by an arbitrary amount. Instead, the fairway should share nodes with the green with no overlap
Examples
LidarKing is just one person that has already done 1000 changesets over the past year and most of them have some serious problems. Not responsive to changeset comments
- They are drawing duplicate ways on top of already existing highway ways and tagging them as golf=cart_path (https://osmcha.org/changesets/114794723)
- Drawing ad-hoc building shapes that don’t resemble the reals structures (https://osmcha.org/changesets/113729066/)
- Deleting objects and redrawing them (a lot of time of worse quality then the original) instead of improving the shape
- Overlapping green/fairway/rough polygons
- To avoid drawing multipolygons, they “wrap” polygon around a hole and leave a tiny open gap.
- Drawing duplicate water areas to tag them as water hazards (https://www.openstreetmap.org/way/983686015 )
Kent Shaffer is probably the same person as thelidarking. Received a few zero hour blocks in 2020. No edits since thelidarking started editing. Not responsive to changeset comments
- https://osmcha.org/changesets/82632800 Incorrectly changed road class from secondary to service and added golf tags
- https://osmcha.org/changesets/82734831 Incorrectly changed road to path with golf tags
- https://osmcha.org/changesets/76230264 Moved underground features out of the way of the golf course
- https://osmcha.org/changesets/83057728 Broke admin boundaries

- https://www.openstreetmap.org/changeset/132655099 Mapping no longer existing golf courses. Got called out and reverted, tried to re-add bogus golf course anyway while being rude to the reporting user. Left with comment "go ahead and delete it if you dont like it. I have the data I need." and then deleted their account. (discussion)
Code for finding
[out:csv(user,ways)][timeout:2500];
(
way(changed:"2021-12-01T23:49:07Z")[golf];
);
for (user()){
make stat
"user"=_.val,
ways = count(ways);
out;
};
