I have noticed Precision and Accuracy being mentioned in the same
context but I believe the two are not the same.
Accuracy (to me) is how close a point is located to it's actual real
earth location - getting the lat/lng of your house when using a map that
is zoomed to country level will not be as ACCURATE as getting the
lat/lng when the map is zoomed right into street level.
Precision (to me) is the scale at which you are trying to locate -
putting the coordiantes of New York is a PRECISION of city level, and
you could find many people using slightly different coordinates for New
York, but they are all _precise_ for that city.
