GPS is not all that accurate anyway. I live in a maritime community, where
the shoreline hasn't changed, and I cannot tell you how often I walk on
water. ;)

Subject: Re: [LegacyUG] GPS lat and long format
I'm not surprised that the online locator is wrong. That information is
only as good the underlying source data. The locations that the online
mapping serices (and your GPS) use are from maps that may or may not be
accurate. Urban areas that justify the time/expense of an actual
drive-through are usually accurate as of the date of the drive-through.
Less urban areas are often not that accurate - if the county surveyor
publishes a map that says there's a road from Point A to Point B, the
online services and GPS vendors will use that map as the basis for their
products - whether the road actually is there or not :-(
State maps may not be any more accurate, I've had a GPS tell me that I'm
going the wrong way on a 4 lane highway with a 50 foot wide median - which
is well outside the margin of error of the GPS. The original map has the
curve in the road starting some 200 feet from where it actually starts.

I used the GPS converter the other day and it put my location of a
cemetery in the middle of the Hudson River. I had to move the push pin
manually to a spot I thought the cemetery should be in, in the middle of
the woods.
