GPS / Mapping
(1) Introduction
- Read the chapter in the Sourcebook for Teaching Science on mapping (Chapter 21).
- Read the GPS manual and lessons on using Google Earth.
- Familiarize yourself with all of the functions on your GPS device
(2) Collect Data
- Take a "hike" around CSUN, your school, or a field trip site
- Record the GPS coordinates for 8 or more waypoints.
- Note - GPS coordinates may be given degrees, minutes and seconds, or in decimal units. To convert to one, use the following converter.
The following measurements are the same
34.241231,-118.530759
34 14.473859, -118 31.84554
+34° 14' 28.43", -118° 31' 50.73"
- Note - GPS coordinates may be given degrees, minutes and seconds, or in decimal units. To convert to one, use the following converter.
- Take digital photos of each of these locations. Sample photos for class.
- Upload your photographs to your Picasa web album.
(3) KML/KMZ file - Google Earth
- Label and plot these waypoints using Google Earth.
- Post your kmz Google Earth file on your website. Examples.
- Plot the route and calculate the total distance traveled. Include a picture of your route in your website.
(4) Plotting your route - Google Maps
- Integrate the photos and your route with Google Maps. (examples)
(5) Discussion
- Summarize the scientific and mathematics principles used in GPS.
- Give a description of how you could use GPS in your class.
