The Studio

The Studio can't plan Mammoth Dunes hole by hole yet.

We hold its scorecard, but nobody has traced its holes: the bunkers, water and fairway edges a plan aims around.

It plans 4,578 courses hole by hole today, and it charts your bag anywhere.

  • The approach, planned A Studio approach map on the aerial photo: a lob wedge aimed at the island green, its spread drawn as a dashed ring over the water, and the side it most often misses. Example from another course: hole 15, Resort tee, Stadium Course at TPC Scottsdale
  • The green, from LiDAR A Studio green view on the aerial photo: arrows for the slope a LiDAR survey measured, the area a cup could be cut, and the safer side to miss. Example from another course: hole 15, Stadium Course at TPC Scottsdale
  • Every shot, tee to green A Studio plan on the aerial photo of a desert par 4: the driver off the tee and a 7-iron into the green between the bunkers, each shot with its landing spread drawn as a dashed ring. Example from another course: hole 2, Resort tee, Stadium Course at TPC Scottsdale

A published figure is compared only against the courses that publish it too, which is why the totals differ from row to row — a state's length field is the courses with a scorecard, not the courses in the state. Height above sea level is the exception: we derive it from a coordinate, so its field is very nearly every course we render. Ties share an ordinal and are marked =. How this is computed →
