July 2, 2010 Reprints No Comments Posted by ls7454 on Jul 2, 2010 8:40 pmI have a handheld Garmin that utilizes WGS 84. Can this be converted to NAD 27 or 83? Can you leave the datum type blank and put a note that says it was obtained via WGS 84? Did you enjoy this article? Click here to subscribe to POB.
