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

3. Presentation Overview 1. Introduction 2. Methods and Data 3. Data Analysis 4. Results and Discussion 5. Conclusion and Recommendations

4. 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

5. 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

6. Precision

7. 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

8. Receiver Comparison

9. Lessons Learned 1. Interference: trees! 2. Dress for weather 3. Bring extra batteries 4. TIME!

10. 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.

11. Final Results Google Earth
