1. Loading a Data Dictionary
Prior to going outside with your GPS rover to collect data for your school map, you must load a data dictionary onto your rover. A data dictionary is a digital list of point, line, and area features along with their associated attributes and values that will be collected during a field session.

2. Here, we have both the rover and your transfer cable.
Connect your communications cable from Geo II to the computer with Pathfinder Office.
2. Make sure you are in “Data Transfer” mode on your Geo II.

3. Normally you will create your own data dictionary
Normally you will create your own data dictionary. However for the purpose of this lesson, the data dictionary has been created for you using Trimble’s GPS Pathfinder Office application.
If you haven’t done so already, you must download the data dictionary created for you.
