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".

Ok.

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.


If I understand you correctly, the "TIFF" option does not produce geotiff
info, but does produce the graphical plot of the track. The "GeoTIFF
without plot" option produces the geotiff without the graphical plot. This
is indeed the "enhancement" I was talking about, thanks

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


I like having the sectional boundaries chosen to include the specified
track. The plot is not as important, as Oziexplorer does that part very
well.

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.


Where AM I headed?

I'm saying, give me the sectional whose boundaries are chosen to include the
specified airports, in a similar way as it works with the plot above.

Thanks Kyler!

Cheers,
John
