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.
