Hole 9
Par 4 · Index – · Hill CourseThe green · from the map
Centre, front and back are measured; the caddie in the app reads the same three points. Green depth 30 m along the line of play.
The ground · from open elevation data
Tee 14 m above sea level, green 35 m, and 21 m between the highest and lowest point of the walk. Uphill is played as the distance plus the climb; downhill as the distance minus two thirds of the drop — the rule caddies used before rangefinders, and near enough on a still day. Sampled every ten metres along the line of play from Copernicus DEM GLO-30, a thirty-metre model of the whole world, accurate to about 4 m. It reads the top of what is there, so a tree-lined tee can read high. Copernicus DEM © DLR/Airbus, provided under Copernicus by the European Union and ESA. The same numbers are in the open data.
