Laboratory Exercise 4
Data for a Feature Position
Global Positioning System and GIS, An Introduction", Michael Kennedy, Ann Arbor
Press, 1996, Part 2 ISBN 1-57504-017-4.2,
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 a data point (as in Laboratory
Exercises 1 and 2) using the GeoExplorer II unit and to record attribute
data for the point using a data dictionary for later use in GIS.
For more information on these concepts, refer to the Trimble
