TO THE APP
Long Marsh is a golf course in the United States. 18 holes are surveyed here from OpenStreetMap, 7,091 yd6,485 m of playing length in total. A par is on record for 9 of the 18 holes, which is not enough for a total. The longest hole is number 10 at 576 yd527 m, the shortest number 3 at 180 yd165 m. Worked out in advance: the distance to the front and the back edge of the green for 10 holes as well as the carry distance over 31 bunkers and 12 water hazards for 16 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.
Yardage book for Long Marsh. 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.

For 18 of the 18 holes the elevation profile is calculated. Hole 7 has the most cumulative elevation change along the played line: 5 yd (2 yd up, 3 yd down; -1 yd net tee to green).Hole 7 has the most cumulative elevation change along the played line: 5 m (2 m up, 3 m down; -1 m net tee to green). The basis are official elevation models (US-3DEP).
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 2026-09-18.
