  1. Golf Course Distance Analysis Brad Herried Jordan Gonnering

  2. Introduction “Golf is not, on the whole, a game for realists. By its exactitudes of measurement it invites the attention of perfectionists” -Heywood Hale Broun, American Sportswriter

  3. Objectives • Repeatedly measure (for accuracy) location of tee, middle of fairway, and green • Calculate distances of holes using latitude and longitude of measurements • Compare measured distances to those posted at course

  4. Site Selection • Odana Hills Golf Course, Madison, WI • Par 72, 6572 yards from Blue Tees • One of four City of Madison owned golf courses

  5. Data Sources/Software • GPS data: collected with Garmin receivers • Satellite Image: WisconsinView download portal • Road Layers: USGS Tiger files • Data acquired into ArcMap using Minnesota DNR’s shapefile creator

  6. Methods • Using two GPS handheld receivers, measurements were taken in 1 minute intervals at each hole • 15 measurements at tee • 40 measurements at fairway (200 yd marker) • 15 measurements at green • Data was collected at holes 1, 2, and 7 (par 4, par 5, par 3)

  7. Example A A B B 15 readings 20 readings 15 readings

  8. Data Analysis - Overview • After these positions were recorded into the GPS as waypoints, they needed to be averaged to find the most accurate point • Data was downloaded into ArcMap and statistical analysis was completed to find standard deviation and average for (x,y,z)

  9. Data Analysis - Overview • With these averages computed, an (x,y,z) coordinate is available to compute distances for each of our tee, fairway, and green locations • Using the distance formula, calculated distances for each hole • (tee to fairway) + (fairway to green) = hole distance • Compared these distances to what the golf course provides

  10. Data comparison • After finding the mean easting and northing coordinates, standard deviation and variance were calculated to best describe accuracy

  11. Data comparison

  12. Spatial Representation • To best accompany our results and comparisons, maps show our spatial accuracy • Maps display holes 1, 2, 7 and zoom into areas for best viewing of data • Notice scale bar and accuracy standards

  13. Discussion • Accuracy was maximized by using multiple readings and multiple receivers • Distances were within ten yards, but when considering standard deviation, results were not as accurate as hoped • By comparing this to ground truth (yardage measurements by course), we found a fairly accurate hole measure

  14. Points to consider • Possibility to measure more holes • Time constraint? Golf course availability? • Taking more measurements leads to better accuracy (over time) • Distances measured on ground or through the air? Which is more vital to golfers? • New advances in golf cart GPS makes this sort of testing obsolete

  15. Thanks!
