Jeppesen database

[Brian Lloyd <brian@lloyd.com>]

Dave Bridgham <dab@froghouse.org> (also on this list) and I purchased the
sample data kit from Jeppesen for their database.  This kit contains a
rather large book of all the record formats and sample data of all the
record types on floppy.  It is enough to allow you to write and test
software that will accept the Jeppesen data as input.  As I recall, it was
about $150(US) for the kit.

It was very enlightening.  The most obvious thing is that the format is
clearly intended for mainframe systems.  Heck, it looks like input data for
a COBOL program (which is probably what it is).  There is a *LOT* of data
available, a lot more than I would have expected.

So, for people planning to play in this area, it might be worthwhile to
play with the Jeppesen data just to get a feel for its value.  Sometimes it
is just worth it to buy clean data than to scrounge for dirty stuff and
then have to go to all the trouble to clean it up.
