GPS Loc as Meta Data for Photos

Why isn’t GPS Latitude and Longitude saved into the meta data of a digital picture when it is taken? Wouldn’t’ a compass and level also give great meta data? (facing 20 degrees from north at a 1 percent incline).

Throw in a 1-button-push publishing and you could create the most amazing maps mashup on the Net with a logical extension to video (same idea - encode per frame or minute) to create a virtual reality that’s based on reality.

An idea like that would surely already be patented – right?
