How does StreetView determine which direction is north?
I have a series of panoramas with links between them. These panoramas have GPS coordinates associated with them and I use them to calculate the compass bearings between two links.
However, it seems that the links themselves are being rendered in arbitrary directions regardless of the heading value.
In my panorama options, I've set the default heading to 0. If this is combined with a panorama heading of 0, the view is rendered from the center of the panorama. Unfortunately, as my link bearings are based off GPS coordinates, if there is no constant north value, the links get rendered all over the place.
How would I solve this?

You probably need to adjust the originHeading on your custom panoramas.

Thank you. But what is the difference between originHeading and centerHeading, and how does that affect the direction of the links?

My bad, originHeading doesn't exist anymore and has been replace with centerHeading. CenterHeading is the heading of the view at the center of the custom panorama you created. So if the middle of the panorama image is the North view with West to the left and East to the right, set centerHeading to 0.
