Green contour map of Ontario in Ontario, New York — 203 elevation contours at a 3-inch interval with fall-line arrows, traced from 1-meter lidar — One of 20 mapped greens at Ontario, drawn from GolfCore's contour data baked from USGS 3DEP 1-meter lidar, in the same colors the app uses. Elevation bands run cool-low to warm-high; white lines are contours at a 3-inch interval, and dark arrows point down the fall line.

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. Clubs correct their own data in the app.

What GolfCore has for Ontario

GolfCore's library covers Ontario Golf Club green by green: 20 putting surfaces traced with 203 elevation contours from USGS 3DEP 1-meter lidar. The steepest measured slope on these greens tilts at 8.5 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. Ontario Golf 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.
