In OpenStreetMap this club has more holes than a single round, or hands out numbers more than once. Which hole belongs to which course is not in the data: the holes carry no golf:course:name. Where that tag is present we separate the courses and show them one by one. Here all holes stand together, and whoever writes the book makes the choice. Tagging the holes in OpenStreetMap settles it for everyone.
River Club of Mequon is a golf course in the United States. 28 holes are surveyed here from OpenStreetMap, 9,733 yd8,898 m of playing length in total. No hole has a par on record. The longest hole is number 8 at 564 yd516 m, the shortest number 10 at 69 yd63 m. Worked out in advance: the distance to the front and the back edge of the green for 28 holes as well as the carry distance over 67 bunkers and 10 water hazards for 28 holes. For 28 holes the elevation change between tee and green is on record as well.
Every hazard carries two numbers: the first reaches its near edge, the second carries past it. Drawn from OpenStreetMap, exactly as the app draws it.

For 28 of the 28 holes the elevation profile is calculated. Hole 3 has the most cumulative elevation change along the played line: 9 yd (1 yd up, 8 yd down; -7 yd net tee to green).Hole 3 has the most cumulative elevation change along the played line: 11 m (2 m up, 9 m down; -7 m net tee to green). The basis are official elevation models (US-3DEP).
Two numbers to every hazard: the first reaches its near edge, the second carries past it. Land between the two and you are in it.

The basis is the map of this course in OpenStreetMap. Lengths, distances to the green edge and carry distances are calculated from it, not copied: every hole is projected onto its line of play and the arc length from the tee is counted. This replaces neither an official course measurement nor the club's scorecard. If you spot a mistake you can report it through the course page in the app, map it in FairwayMapper or correct it in OpenStreetMap straight away. Data as of 2026-09-18.

The club material is still waiting on OpenStreetMap: 28 holes are drawn, not a full round of 9, 18, 27 or 36; the gap is listed above, under par. You know your course better than any stranger: in OpenStreetMap that is an hour of work.
