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 |

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 27 of the 27 holes the elevation change between tee and green is calculated. Hole 19 climbs the most, by 2 m between tee and green. Hole 20 drops the most, by 3 m. The basis are official elevation models (DE-SH).
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. Data as of 2026-07-30.
