Reference "The Global Positioning System and GIS, An Introduction", Michael Kennedy, Ann Arbor Press, 1996, Part 2 ISBN 1-57504-017-4.2,

Background

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 site.
