Guyan Golf and Country Club is a golf course in the United States. 18 holes are surveyed here from OpenStreetMap, 5,874 m of playing length in total, at par 71. The longest hole is number 11 at 510 m, the shortest number 12 at 146 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 29 bunkers and 2 water hazards for 16 holes. For 18 holes the elevation change between tee and green is on record as well.
Yardage book for Guyan Golf and Country Club. 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.

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 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 change between tee and green is calculated. Hole 2 climbs the most, by 17 m between tee and green. Hole 5 drops the most, by 20 m. The basis are official elevation models (US-3DEP).
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.
