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.
| TAG | MISSING ON | WHAT FOR |
|---|---|---|
| par | 16 of 16 holes | Club choice and expectation |
| handicap | 16 of 16 holes | Stroke index, net scoring |
| ref | 16 of 16 holes | Hole number, right order |
Holes without ref appear in the table below under numbers we assigned by length; the numbers on the course need not match.
In OpenStreetMap this belongs on the individual hole, not on the course; anyone who plays here can add it there for everyone: edit in FairwayMapper · look at the course in OpenStreetMap · open the editor right away.
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.

For 16 of the 16 holes the elevation profile is calculated. Hole 6 has the most cumulative elevation change along the played line: 18 yd (14 yd up, 4 yd down; +10 yd net tee to green).Hole 6 has the most cumulative elevation change along the played line: 15 m (12 m up, 3 m down; +9 m net tee to green). The basis are official elevation models (EU-DEM).
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 2026-09-25.

The club material is still waiting on OpenStreetMap: 16 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.
