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. 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.

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. Data as of 2026-08-19.
