have any indicies how is EPSG:3785 different than standard WGS84? I've been
doing coordinate transformation from numerous other CRSes to WGS84 and
everything worked fine with Google Earth/Maps. The most important part
of the process is, naturally, getting correct WGS84 transformation
parameters in first place. BTW, decimeter-precision range is out of
question due to GE/GM aerial imagery scale which is, if I recall
correctly, 1:5000 (m) at best.</SPAN><o:p></o:p></P>
