Laboratory Exercise 5
Intergrating GPS Data with ArcView GIS
Reference "The Global Positioning
System and GIS, An Introduction", Michael Kennedy, Ann Arbor Press,
1996, Part 2, ISBN 1-57504-017-4.
This laboratory consists of an introduction to the use of the Trimble,s
GeoExplorer II mapping system consisting of a pocket sized
GPS data collector and Pathfinder Office - GPS processing software.
In this exercise, you will learn how to acquire data points using a
moving GeoExplorer II unit and then transferring the corrected
GPS data to ArcView as new theme in an existing view.
For more information on these concepts, refer to the Trimble

How many points were actually collected, as compared with the number
expected? Document the log rate and number of points taken calculations.
How much error (distance) is there between the GPS data for a point
and the base map location of the point? Choose points easily discernible
like an intersection. Is there a pattern to the error?
Comment on the accuracy of the GPS data as compared to the base map.
If there are discrepancies, give possible reasons.
If there were discrepancies, how would you re-run the experiment to
If this from for some reason does not work, submit your answers by way
