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 11, there is
  no bias

Lessons Learned

1. Interference trees!
2. Dress for weather
3. Bring extra batteries
4. TIME!

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.
