Google Map latitude/longitude not accurate in Apple Map

Hi there.

I do receive lat & long information to be able to show routing on my map. I do receive these information from Google by http://maps.googleapis.com/maps/api/directions/xml service. Whatever I acquire that shows up on the right spot on the Google map. All good.

However, If I bring up the Apple map, these lat and long information are pointing different places which are inaccurate. Basically, the Apple map intersects these address wrongly on the map.

Does Apple use different latitude and longitude information to display on the map? OR any chance that the Apple map may use slightly different location information ??

thank you very much.
