What GolfCore has for Don Valley

GolfCore's library covers Don Valley Golf Course green by green: 17 putting surfaces traced with 180 elevation contours from 1-meter national lidar elevation data. The steepest measured slope on these greens tilts at 7.7 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. Don Valley Golf Course 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.
