The greens here
15 greens at Hagley have been mapped from the national LiDAR survey — 5,047 m² of putting surface altogether, with a median green of 306 m². The national median is 397 m², so these run 23% smaller than average.
- Steepest green: green i, averaging 3.4% and falling west.
- Flattest green: green g, at 0.7%.
- Most internal fall: green i, 0.92 m between its low and high point.
- Largest green: green o, 687 m².

“Fall” is the height difference between the lowest and highest point of the putting surface. “Avg grade” is the best-fit plane across it — a green can average 2% and still have a shelf on it, which is what the app shows and a table cannot.
Where these numbers come from
Heights come from Land Information New Zealand’s 1 m LiDAR elevation survey (Christchurch, 2024-2025), published openly under CC BY 4.0. Green outlines and hole numbers come from OpenStreetMap under the Open Database Licence. Slope uncertainty on this course works out at ±0.15%.
Slope is measured. Break is modelled — the read in the app is a physics simulation of a ball rolling over the measured surface, and it knows nothing about grain or moisture. The survey predates any green rebuilt since 2025. More about how this is made.
