Yesterday, I published a post about creating QR codes for GPS locations to build scavenger hunts. In that post I mentioned an app called GPS Essentials that a friend turned me on to. I spent some time last evening having fun testing out GPS Essentials.
In addition to the expected features of showing your current latitude and longitude coordinates, GPS Essentials offers a bunch of other useful features. Using GPS Essentials you can measure your current altitude, measure distances, and record your tracks. You can export your tracks and waypoints as KML files to use in Google Earth and Google Maps. You can also import KML and GPX files to use in GPS Essentials to navigate to various locations.
Combine the use of QR-GPS Plugin with GPS Essentials to create and carry-out scavenger hunts. Use the combination to record and plan walking tours for your next field trip. Or use GPS Essentials to teach students basic lessons on navigation (if you’re taking students on actual hikes, long bike rides, or paddling trips, don’t use GPS Essentials as a replacement for a real GPS unit and maps).
