Ruhr-Golf is a golf course in Germany. 10 holes are surveyed here from OpenStreetMap, 1,935 m of playing length in total. A par is on record for 9 of the 10 holes, which is not enough for a total. The longest hole is number 4 at 329 m, the shortest number 9 at 98 m. Worked out in advance: the distance to the front and the back edge of the green for 9 holes as well as the carry distance over 5 bunkers for 4 holes. For 10 holes the elevation change between tee and green is on record as well.
Yardage book for Ruhr-Golf. 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.
OPEN THE COURSE IN THE APPReading needs no account. Writing your own book does.
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.
| TAG | MISSING ON | WHAT FOR |
|---|---|---|
| par | 1 of 10 holes | Club choice and expectation |
| handicap | 1 of 10 holes | Stroke index, net scoring |
In OpenStreetMap this belongs on the individual hole, not on the course; anyone who plays here can add it there for everyone: look at the course in OpenStreetMap · open the editor right away.
All figures in metres. The length follows the line of play from the back tee to the middle of the green and takes a dogleg with it. Carry distances count from the tee to the near edge and to the far edge of the hazard. The stroke index ranks the holes by difficulty from 1 to 18 and decides where net strokes fall.

For 10 of the 10 holes the elevation change between tee and green is calculated. Hole 6 climbs the most, by 17 m between tee and green. Hole 10 drops the most, by 16 m. The basis are official elevation models (DE-NW).
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 or correct it in OpenStreetMap straight away.
