  1. GLE 444: Practical Applications of GPS Mapping the Henry Vilas Zoo JON HENNING KEVIN KOWALCHUK ALEX SUMMITT

  2. Presentation Overview • Introduction • Methods and Data • Data Analysis • Results and Discussion • Conclusion and Recommendations

  3. Introduction • Objectives: Create a virtual ‘Vilas’ zoo experience • Motivation: Single map to pre-plan a visit • Accuracy: 1-10 m (~5 m) • Audience: Henry Vilas Zoo visitors • Location: Madison, WI

  4. Methods and Data • Equipment: • 3 hand-held GPS units, digital camera, laptop • Duration: • 27 waypoints • 10-15 minutes a piece, total: 7 hours • Type of Data: • Position coordinates • Digital photographs • Written descriptions

  5. Precision

  6. Precision Comparison of Longitude and Latitude • Want to determine if we have better measurements of either latitude or longitude • Since all data is clustered around 1:1, there is no bias

  7. Receiver Comparison

  8. Lessons Learned • Interference: trees! • Dress for weather • Bring extra batteries • TIME!

  9. Specifications Met • Most points fell within the accuracy range of 1 – 10 m • Four points in particular varied greater than the expected 1 – 10 m accuracy • One point could not be taken due to interference • Google Earth showed accurate locations to interpret between different animal exhibits and locations.

  10. Final Results Google Earth
