I am struggling with the following problem and can not find any solution in the Goolge Maps API docs or in the net, therefore I will try to post my question here:
I was using Googles Static StreetView Image API, where you can pass as a location a long/lat or a string with a postal address. In my case I was always using the string approach that contains in most cases the address with a housenumber. I was astonished by the results of the returned image, which was in most cases perfectly oriented in the direction to the searched address.
Now I wanted to give the JavaScript API for StreetViews a try. It works perfectly fine with the only available interface for a location through specifing the address through long/lat values. Through the optional pov parameters the heading can be specified too. But in case you want to initialize the StreetView with a postal address with a housenumber you are lost with that API. The only way is to geocode the postal address to a long/lat value through the Geocoding API but with the handicap of loosing the heading information. As a final result the initial StreetView image was completely different oriented in such a case.
I checked again the Static StreetView Image API and found following comment to the heading member:
heading (optional): ... If no heading is specified, a value will be calculated that directs the camera towards the specified location, from the point at which the closest photograph was taken.
Is there anything I can do here? How can I find the perfect heading between the position of the made photo to the location I am looking for? It seems only Google can do this through some internal magic for the Static StreetView Image API.
