In my last article (on figuring out the name for Antora Peak) I noted the discrepancy between the GPS coordinates provided by my iPhone and the actual location where I took the photo (graphic above). They were off by about 20-30 feet. You can test the accuracy of the GPS information provided by your camera/smartphone. This article will show you how.
