While I'm new at geocaching I, like others, routinely encounter discrepancies between the posted coordinates, Google maps, Google Earth, and reality. As I'm an experienced aircraft and marine navigator I've wondered about the lat/lon accuracy of both Google Maps and Google Earth. Does anyone have any insight about this?
I've noticed with Google Earth that a single geocache will 'jump' around the map as the map is zoomed in/out. I assume this is an artifact of the software and so I don't use Google Earth much to help me find caches.
In Google Maps this 'jumping' does not seem to occur. Yet Google Maps reports cache locations other than where the cache, in fact, is. This could be an issue with the cache's posted coordinates OR it could be an issue with Google Maps. Does anyone have any insight into the lat/lon accuracy of Google Maps?
