google maps geocoder - point on a street

问题:

If I use google maps geocoder to find a point of an address - I usually get a point in the middle of the building (roof top)

example:

https://maps.google.com/maps?q=350+Alabama+Street,+San+Francisco,+CA,+United+States&hl=en&ll=37.764842,-122.412077&spn=0.001497,0.002661&sll=37.794661,-122.425718&sspn=0.001496,0.002661&oq=350%2BAlabama%2BStreet&hnear=350+Alabama+St,+San+Francisco,+California+94110&t=m&z=19

Geocoder request:

http://maps.googleapis.com/maps/api/geocode/json?address=350+Alabama+Street+San+Francisco&sensor=false

so the point is actually in the middle of Harrison and Alabama streets

But I need to get a point that is located on Alabama street line

Is there a ways to do that ?

You may request the directionsService instead of geocoding, this should return a location placed on the street when used with google.maps.TravelMode.DRIVING
