Looks like I've missed the most interesting part while I was visiting a
customer  :-)

In some way our elevation/height (for published obstacles/obstructions)
data has always to be some sort of a 'fork' for several reasons. 
Probably the most obvious one is being the fact that different
authorities are having different habits of specifying the highest
spots.

Some authorities are adding 500 ft clearance to the physical top of an
obstacle for their published obstacle elevation, some don't ....  even
though a human definition of the highest spot would be pretty
unambiguous, things are getting rather complicated after passing
'authoritative' processing  :-)

Cheers,
