The USGA is working on integrating GPS within the GHIN Mobile App. This will include Course Maps that allow the user to get touch-point GPS distances to anywhere on the course and distance to the center of the green for thousands of courses worldwide.
They will add a new flow for users to "Play with GPS" where they can enter/post their hole-by-hole score while using GPS features & viewing the Course Map. These features will also be made available to golfers who have gone down the "Post Score" flow when posting a hole-by-hole score or hole-by-hole score with stats. Additionally, users can also "preview" a course or use these features outside of playing/posting.
The USGA is looking to add this feature in an App update in mid-July. For a detailed overview of the upcoming offering, click here.
