In principle the orientation can often quite reliably be determined from 
elevation data - this is of course not so easy to do with the normal 
rendering framework.

In general orientation of a saddle is also a function of the scale you 
look at - for example this:


has an east-west orientation when you look at it closely but on a coarse 
scale it is a north-south crossing.
