For 9 of the 9 holes the elevation profile is calculated. Hole 1 has the most cumulative elevation change along the played line: 6 yd (0 yd up, 6 yd down; -6 yd net tee to green).Hole 1 has the most cumulative elevation change along the played line: 8 m (1 m up, 7 m down; -6 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.
