Okay, that is a great starting place, I think I could make a go from
there.

Another issue was mentioned, the "garden shed accuracy problem," and
someone suggested:

"There are settings in there you can tweak
on the encoding used by the GeoXml class
.. the default values used are
geoxml.verySmall = 0.0000001;
geoxml.ZoomFactor = 2;
geoxml.NumLevels = 18;
set them on your GeoXml object
before calling parse"

How would you do this - and does it seem likely that altering these
constrainst would resolve the inaccuracies that I am observing WITHOUT
having to reparse the data manually?
