The greens here
9 greens at Houhora have been mapped from the national LiDAR survey — 2,199 m² of putting surface altogether, with a median green of 235 m². That puts them in the smallest tenth in the country — 41% below the national median of 397 m².
- Steepest green: hole 4, averaging 4.9% and falling south-east.
- Flattest green: hole 7, at 1.8%.
- Most internal fall: hole 2, 0.95 m between its low and high point.
- Largest green: hole 5, 268 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 (Northland, 2018-2020), 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 2020. More about how this is made.
