Abstract: A method and system for use to either or both provide information on golf courses to players and for course design and routine modification. The information provided is on golf courses as to course difficulty, hole length and slope, pin and tee location, etc. for the current day or any given day in the future, and for course design and routine modification of pin and tee location to maintain course difficulty during pin and tee movement by maintaining overall course slope while altering the slope on each hole. The method and system involves using global positioning satellites to plot golf courses including the slope, topography and other parameters thereof, and then microprocessors and programs to define future tee area and pin locations which are defined by a time sensitive formula such that access is available to the actual future locations on a set date in the future.
