[ gpsdrive ] Goole maps projection

Hi,

saw this post (read the thread, specifically Gerald's corrections) which
claims to specify the map projection Google uses and PROJ.4 conversion
terms. If it works it'll be a much better way of deriving the scaling
factor versus the "tweak until not so bad" approach.

PROJ.4:  http://proj.maptools.org
 (sibling of GDAL; very well respected & widely used)
