Errant Golf Ball Analysis
If there is an errant golf ball issue, how does one determine the theoretical severity of the problem along with the recommended solutions?
1. Site Analysis
Firstly, a site analysis is performed, most of which can be done using Google Earth data. Distances and angles are measured along with any elevation changes (topography). Prevailing wind and temperature data is researched.
2. Golf Ball Trajectory Software
Software is utilized to simulate errant golf ball trajectories. This software predicts trajectories in very close agreement to the trajectories measured by the Trackman and Flightscope Radar Golf Monitors. The simulations can determine the lateral distances (left and right) as well as golf ball height at any distance with inputs of golf club speed, loft, backspin, etc.
3. Real golf ball data by a full range of golfers is used to produce scatter plots shots off the tee and/or for any club and distance. A large portion of the shots is found to end within a cone of a certain angle. Better golfers tend to hit their shots within a narrower cone.
Using this data, one can calculate the percentage of golfers that will likely hit outside the cone and thus become a dangerous, errant golf ball that might land onto an adjacent property. The Golf Ball Trajectory Software can then determine the golf balls' heights and thus the required heights of netting to contain such shots.
One can calculate a containment percentage based on the height of the netting.
See sample images below showing the scatter of Tees Shots and the scatter of iron shots to a green.
