I am thinking about using python or C++ in conjunction with google's geocoding API. Since geocoding is the process of turning street addresses into coordinates, I was wondering how google does this. I am looking for something that will give me coordinates that are around 50 meters away from the entrance of the location at a specified address. There are a few problems with this when you use google maps however. If you aren't doing it manually, sometimes google maps will place a marker for an address just on the road and not over the place (especially for addresses in malls, places far off the road, etc). Does the geocoding api give you more accurate coordinates or does it simply copy the coordinates of what a google maps marker would give you?

I hope this makes sense.

Thanks.
