The ground · from open elevation data

Tee 5 m above sea level, green 5 m. 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.
