The reason for this is that the street view POV is, by default the direction the truck was facing when the image was shot (go figure). You need to get the location of the truck and the location of the house and calculate a "heading" from the first location to the second:
// adrloc=target address
// svwloc=street-view truck location
svwService.getPanoramaByLocation(adrloc,svwdst,function(dta,sts) {
if(sts==google.maps.StreetViewStatus.OK) {
var svwloc=dta.location.latLng;
var svwhdg=google.maps.geometry.spherical.computeHeading(svwloc,adrloc);
var svwmap=avwMap.getStreetView();
svwmap.setPosition(svwloc);
svwmap.setPov({ heading: svwhdg, pitch: 0 });
svwMarker=new google.maps.Marker({ map:svwmap, position: adrloc });
svwmap.setVisible(true);
}
else {
...
}
Another trick/trap using street view is that you need to obtain the closest street view to your address location by repeatedly calling getPanoramaByLocation with an increasing distance until you are either successful or reach some maximum distance. I solve this using this code:
var SVW_MAX=100; // maximum street-view distance in meters
var SVW_INC=10; // increment street-view distance in meters
var svwService=new google.maps.StreetViewService(); // street view service
var svwMarker=null; // street view marker
// NOTE: avwMap is the aerial view map, code not shown
...
resolveStreetView(avwMap.getCenter(),SVW_INC);
...
var resolveStreetView=function(adrloc,svwdst) {
svwService.getPanoramaByLocation(adrloc,svwdst,function(dta,sts) {
if(sts==google.maps.StreetViewStatus.OK) {
var svwloc=dta.location.latLng;
var svwhdg=google.maps.geometry.spherical.computeHeading(svwloc,adrloc);
var svwmap=avwMap.getStreetView();
svwmap.setPosition(svwloc);
svwmap.setPov({ heading: svwhdg, pitch: 0 });
svwMarker=new google.maps.Marker({ map:svwmap, position: adrloc });
svwmap.setVisible(true);
}
else if(svwdst<SVW_MAX) {
resolveStreetView(adrloc,svwdst+SVW_INC);
}
});
}
