Introduction
to GPS Data Collection and Processing -
GPS Fundamentals and Integration with
GIS using ESRI's ArcPad & Trimble Receivers
Course
ID: GPS-401
June
14 - 15, 2006, 8:30 A.M. to 5 P.M. (2 Days)
Allied Business Systems, Main Computer
Lab | 10604 NE 38th Place, Kirkland, WA
Instructors:
Jim Lahm, Electronic Data Solutions; and Stefan Freelan, Western Washington University
Description:
This workshop provides an introduction
to the concepts and applications of GPS for data collection using Trimble hand-held
GPS receivers and ESRI's ArcPAD. Through a combination of lecture and hands-on
field and computer exercises participants will gain a working knowledge of how
GPS data can be collected and used for a variety of applications. The emphasis
for this two-day workshop will be on the fundamentals of GPS data collection,
the use of ArcPad and GPS Correct, and the incorporation of GPS data into ESRI's
ArcGIS environment with the GPS Analyst extension. Participants will work in groups
with Trimble GeoXT GPS receivers equipped with ArcPad and GPScorrect during daily
field sessions.
Background:
ArcPad is a field GPS data collection, storage and editing program designed
for use in a Windows Pocket PC or Windows Mobile device.
-
GPScorrect is an extension for ArcPad that collects the necessary measurement
data from the GPS satellites and allows the user to apply spatial corrections
to the raw GPS data back in the office. Corrected
GPS data has sub-meter horizontal accuracy according to the specifications of
the Trimble GeoXT. Uncorrected data is subject to horizontal errors of up to 15
meters.
-
GPS Analyst is an
extension for ArcGIS (8.3+) that allows the user to work with Trimble GPS data
in the ArcGIS environment. It provides for the processing of GPS data to achieve
maximum spatial accuracy, in addition to feature class validation, rebuilding,
editing, and the analysis of GPS statistics to insure high spatial quality.

Intended
Audience: This course
is intended for professionals involved with either GPS data collection or the
incorporation of GPS data into GIS. No prior experience with GPS or ArcPad is
required. Step by step instructions and pre-made map projects will be provided
for ArcGIS novices, however, some experience with ArcGIS is recommended (this
workshop is not an introductory GIS course).
After
completing this course, participants will be able to:
- Understand GPS technology (concepts and theory)
- Understand GPS coordinate
systems, datums, and conversion options
- Collect GPS data with ArcPad
- Transfer GPS data off of the receiver
- Use GPScorrect
- Perform differential
correction using the GPS Analyst extension
- Use a Trimble GPS receiver for
basic navigation purposes
- Export/Import GPS data as an X-Y data file with
ArcGIS 9
- Begin spatial analysis within ArcGIS using GPS data
- Understand
some of the applications and limitations of GPS data for spatial analysis
Education
Level: Introductory/Intermediate
Course
Materials: Each participant will receive a book containing lecture
notes, exercises, and reference material.
What
to Bring: Pen or pencil and a water bottle (to reduce waste). Please
wear comfortable clothing appropriate for the prevailing weather. Snacks will
be provided but lunch will be on your own. Participants who have access to a Trimble
GeoXT GPS receiver with ArcPad installed are encouraged to bring their equipment
to the class (including data transfer cradle and cables).
