GPS Coordinates (Geogebra)

This is a Geogebra program for use as a visual aid in the teaching of coodinates for the Global Positioning System (GPS). This program has been designed for use with Geogebra 5.0 (download version). This resource assists the teacher in clearly showing students how latitude and longitude angles are able to define any position on a 3D simulation of the Earth’s surface. Simply enter a specific GPS position (in degrees, minutes, seconds) and the program will show this location on the Earth. The program also shows a 2D represention of the position in vertical and horizontal planes, which can also be dynamically adjusted. The Earth will also spin so students can clearly identify the position from different perspectives or you can manually rotate the Earth to any perspective.

This is a resource that will visually engage your students, improve their comprehension and save you significant effort from trying to represent three dimensions on a two dimensional surface.
