In the US, the Google geocoder is top-notch, and I'd love to use it for
OTP. But there is a big restriction on its use though, ala "the
Geocoding API may only be used in conjunction with a Google map;
geocoding results without displaying them on a map is prohibited."
http://code.google.com/apis/maps/documentation/geocoding/
That said, I'm guessing that Google's intent is more to thwart bulk
geocoding, etc... (and I doubt old-man google would care much about a
transit map with a non-google basemap). Sadly, with no seeming
exception process to that API/GMaps restriction, I will continue to
avoid using the Google geocoder api though.
Take care,
Frank
