Sorry, this one slipped past my radar in the last few days... project
deadlines and stuff...

Now we can't really help with the EGGenerator, but very recently, a full
DEM loader has been added to the repository. Part of the loader is
providing you with full EG rendering. If you choose, you could then plug
that DEM into the ROAM implementaiton that is there. Given another month
or two, that should also then include the navigation code too.

Part of the DEM parser is the requirement to implement the
HeightMapParser interface. Hmm.. unfortunately that doesn't give you the
information you require. However, you could always grab the TypeB record
structures in the file (available from the parser) and look through each
of those looking for Max/Min heights and work out what the highest one
is....
