I bought the National Geographic Topo Backroads for about $50 (covers US
incl Hawaii and Alaska). It is possible to use this to generate a profile or
elevation view if you know your route segments. It has a GPS interface, so
potentially you could use it on a notebook or PDA. It is certainly not
certified for aviation use.

Is there any particular topo map that's suitable for aviation use
(should I say certified?)
