How the greens break
GolfCore traced 15 greens at Observatory from 1-meter national lidar elevation data, with 190 elevation contours at a 8-centimeter interval. The steepest measured slope is 8.1 percent, and the largest rise across a single green is 1.36 m.
In the app the same map sits under your ball on every green, with the fall line drawn to the hole and the wind modeled at your position. At clubs that run GolfCore, the pins the shop sets each morning show up there too.
