What GolfCore has for Long Island

GolfCore's library covers Long Island National Golf Club green by green: 19 putting surfaces traced with 268 elevation contours from USGS 3DEP 1-meter lidar.

Long Island National Golf Club is one of more than fourteen 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.
