O.k., so real Ozi files work. I appreciate knowing that. (I tested with
an NMEA file that I'd converted to .plt. BTW, GPSbabel *can* convert back
to NMEA sentences.)

It does? I've only used it through http://wayhoo.com/index/a/gpsbabel/. I
don't see NMEA in the options list-- am I missing something?

Yes. Get the real thing.

The file format is "nmea".

Enhancement to track-plot: have an option to produce the sectional chunk
WITHOUT the actual track.

That's not an enhancement...that's the only way I can produce GeoTIFFs
right now. (I had it working that way for awhile.) I haven't gotten
to where I can modify an image (using PIL) and then put the geo data
back on it.

So this is useful? It's not much of a "plot" but I've enabled it.

Other enhancement: produce a sectional chunk given two airport id's.

Hmmm...we're getting into less plotting and more chunking. I can see
where you're headed. I'll try to build another tool for specifying
chunks easily.
