OpenYardage
TO THE APP
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.
Mergelhof is a golf course in Belgium. 62 holes are surveyed here from OpenStreetMap, 13,236 yd12,106 m of playing length in total. No hole has a par on record. The longest hole is number 14 at 570 yd521 m, the shortest number 62 at 68 yd62 m. Worked out in advance: the distance to the front and the back edge of the green for 27 holes as well as the carry distance over 84 bunkers for 39 holes. For 62 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.
Yardage book for Mergelhof. In OpenYardage every hole is a drawing, with distance rings, your own notes hole by hole and your club choice. Books by other players can be read, copied and printed as an A6 booklet.

For 62 of the 62 holes the elevation profile is calculated. Hole 14 has the most cumulative elevation change along the played line: 43 yd (0 yd up, 43 yd down; -43 yd net tee to green).Hole 14 has the most cumulative elevation change along the played line: 39 m (0 m up, 39 m down; -39 m net tee to green). The basis are official elevation models (BE-VL, BE-WA).
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 2026-09-14.

The club material is still waiting on OpenStreetMap: 62 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.
