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