- Does a= nyone have an opinion on the acuracy of Google Earth? If i c= an zoom in and see the cache location, place my pointer on tha= t point, can i assume that the designated coordinates are mo= re acurate than my GPSr's? I know there's still the error = of the finder's unit to be accounted for, but at least the hi= der's error has been minimized. ------ Original Message ------ Received: Wed, 02 May 2007 04:29:57 PM EDT From: Mike Lusicic <lusicic@xxxxxxxxxxxxx> To: geocaching@xxxxxxxxxxxxx Subject: [GeoStL] Re: Perfection is hard to achieve - Well, most folks look at only the accuracy of their GPSr (from my= experiencein showing folks), assuming the published coordinates a= re accurate.Even with 15 foot accuracy, if the hider is off 15 feet = to the left and the finder is 15 feet off to the left of that, then that is 3= 0 feet without even 30 foot accuracy showing on your GPSr. If both units= are only getting 30 foot accuracy, then you could be 60 feet away. Of cour= se that is the most extreme example. Of course the better the hider can do, = the less he is going to contribute to the error, thus the method Steve was re= commending for establishing the cache coordinates.

I can easily count several times the cache was away from both of our "Z= ero" points,so I've learned to start looking around from there.

I have = experienced several incidents of people pointing out that a cache is off by 2= 0 to 50 feet.

How fun is pin the tail on the don= key if your hand guides you to the exact spot. Where is the challenge? Most o= ften the difference is 30 feet or less, and geoexperience should teach whe= re to look. I would love feedback on this issue. Am I atleast partly correct = for causes of descrepencies?
