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
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
lessons learned
Lessons Learned
  • Interference: trees!
  • Dress for weather
  • Bring extra batteries
  • TIME!
specifications met
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.
