You can calculate the yaw for the POV automatically if you have the camera location and the building location. There are issues however: 1. if Google doesn't have "rooftop" geocoding in that area the geocoded address will be on the street not where the building is (so it won't be useful for calculating yaw). If the correct location is stored in a database and not retrieved by geocoding the address, this shouldn't be an issue. 2. if the "rooftop" geocode is too far from the street, getNearestPanorama will not find a camera location for you. This page shows the result returned by the geocoder and a set of streetview camera locations around it: http://www.geocodezip.com/example_geo2_panoJ.asp?addr1=591%20Camino%20De%20La%20Reina,%20San%20Diego,%20CA&geocode=1 The result returned by the geocoder doesn't result in a valid location for a camera from getNearestPanoramaLatLng, but there are camera locations available that show the building. Note: in some browsers, the first click on the streetview camera locations doesn't work, it displays a blank infoWindow, subsequent clicks work. You could store both the building location and the streetview camera location in your data base, but I'm not sure what will happen if the streetview locations are updated. -- Larry > My perrson > who has arranged the coding for this has switched to this code here > >http://www.tulsaview.com/Johny-Carinos.html.
