What GolfCore has for Blacknest

GolfCore's library covers Blacknest Golf & Country Club green by green: 18 putting surfaces traced with 124 elevation contours from 1-meter national lidar elevation data. The steepest measured slope on these greens tilts at 8.4 percent — the difference between a putt that dies at the hole and one that runs four feet past.

In the app, players and caddies read the same data live on the course: contour bands with fall-line arrows, wind simulated at the player's position, and pin positions that clubs on GolfCore set each morning. Blacknest Golf & Country Club is one of more than six thousand courses GolfCore has mapped green by green.

For clubs, the same system runs the tee sheet and the caddie yard — assignments off real tee times, SMS confirmations, and a caddie network that spans every club on the platform. Read how caddie management on GolfCore works.
