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.
Great Northern is a golf course in Denmark. 27 holes are surveyed here from OpenStreetMap, 9,533 yd8,716 m of playing length in total. A par is on record for 18 of the 27 holes, which is not enough for a total. The longest hole is number 14 at 601 yd550 m, the shortest number 27 at 148 yd135 m. Worked out in advance: the distance to the front and the back edge of the green for 26 holes as well as the carry distance over 66 bunkers for 25 holes. For 27 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 Great Northern. 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.

All figures in yards, converted from the metre values in OpenStreetMap.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 profile is calculated. Hole 2 has the most cumulative elevation change along the played line: 32 yd (28 yd up, 4 yd down; +24 yd net tee to green).Hole 2 has the most cumulative elevation change along the played line: 30 m (26 m up, 4 m down; +22 m net tee to green). The basis are official elevation models (DK-DHM).
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.
