I have some questions about some of the parameters. Here's an example of the Statue of Libertyhttps://www.google.com/maps/@40.6857974,-74.0453996,237a,20y,12.19h,59.76t/data=!3m1!1e3@40.6857974,-74.0453996 is eye latitude,longitude in degrees decimal237a is eye altitude in meters20y is unknown12.19h is heading in degrees decimal59.76t is tilt in degrees decimaldata=!3m1!1e3 is unknownAnyone able to figure out the meaning of the 2 unknowns? y in Streetview is the field of view, I'm guessing it's the same with Earth mode, but Google doesn't want people altering the FOV value which would explain why it's always reverting to 20y if you try to change it.EDIT: yes, the y value is indeed FOV, looks like half of the horizontal FOV specifically. I noticed that when you zoom in first it widens the FOV (y value gets bigger) then as you zoom in more it goes into Streetview. Problem is if you copy a url with a y value other than 20 it'll simply change it back to 20.
