What GolfCore has for Plum River

Plum River Golf Course in Port Byron, Illinois is in the GolfCore library with its location. Its course map is traced, so the app draws the property, the fairways and the greens. The green contour maps are baked from lidar and this course has not been through that yet.

In the app, players and caddies read the same data live on the course: contour bands with fall-line arrows, and pin positions that clubs on GolfCore set each morning. GolfCore has mapped more than six thousand courses green by green, and the library grows every week.

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.
