Unless I'm missing something fundamental, I think stitching and  
georeferencing the images is quite straightforward given that they  
will be at a known, fixed position from the gps receiver.

 From a more practical point of view there are two further issues:
- there needs to be some compensation for potential differences in  
exposure between shots on adjacent cameras (a KISS approach might  
have 3 parallel cameras for each angle, one with auto exposure, one  
higher, one lower, with post-processing to determine which of the  
shots to use from each camera based on exif tags, histogram analysis  
etc...)
- capture in suboptimal conditions should be avoided - this included  
the obvious such as avoiding precipitation, but also bright sunlight.  
Fortunately northern Europe is blessed with clouds providing many  
hours of lovely diffuse light ideal for photography.

Cheers,

Andrew
