Tammer-Golf is a golf course in Finland. 18 holes are surveyed here from OpenStreetMap, 6,205 yd5,674 m of playing length in total, at par 72. The longest hole is number 12 at 547 yd500 m, the shortest number 9 at 138 yd126 m. Worked out in advance: the distance to the front and the back edge of the green for 18 holes as well as the carry distance over 40 bunkers and 11 water hazards for 18 holes. For 18 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.

Par and stroke index are on record for every hole, so the card is complete. Not every club publishes its scorecard; this one is put together from the open data of OpenStreetMap and is not the club's official card. For a counting round the card from the pro shop is the one that applies.
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 18 of the 18 holes the elevation profile is calculated. Hole 4 has the most cumulative elevation change along the played line: 12 yd (3 yd up, 9 yd down; -6 yd net tee to green).Hole 4 has the most cumulative elevation change along the played line: 10 m (2 m up, 8 m down; -6 m net tee to green). The basis are official elevation models (FI-MML).
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.
