How the greens break
GolfCore traced 19 greens at Mount Si from USGS 3DEP 1-meter lidar, with 137 elevation contours at a 3-inch interval. The steepest measured slope is 6.6 percent, and the largest rise across a single green is 2.9 ft.
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.

Hole data is what GolfCore holds for the course's layout. Picking a tee shows that tee's own yardages, pars and stroke indexes where the club has rated them. Spot a wrong par, yardage or stroke index? Report it from Map Settings in the app, or send us a correction.
