Slope Measuring Answered
I'm interested in making a yardage book for one of the golf courses i play at. The only problem is that i don't know an accurate way to measure the change in distance through elevation. For instance if a shot to a green with no change in elevation requires a 7-iron, then a shot of the same distance that is downhill should require a club that will hit the ball a shorter distance.
My question is, is there a formula of some type that i can enter the rate of change in slope and the distance, and get the actual distance needed for the shot.
