[Xastir-dev] Position accuracy

[Gerry Creager N5JXS]

The compressed positions with resolution of 1 foot are really 
misrepresentations.  Bob B.'s said this, and I've actually agreed with 
him, although not always for the same reasons he stated.

When you're entering data for a position, it's considered good practice 
in the geodetic surveying community to enter the coordinates as 
precisely and accurately as possible.  That way, if there's a subsequent 
loss of precision, it's not for want of good initial data.
