First off, everything inside the 10nm circle on NOAA plates is to scale
- meaning you can indeed georeference them. By "Fly on them" on mean a
system that will use your GPS location and plot your position on top of
the plate.

'To scale' and 'accurately plotted' are not the same thing. If you just want
a general idea, then it might work.

I think it might be worthwhile. I've thought about ways of describing the
georeferencing so that, for example, you could get a reasonable idea of
where you are even when on the 222 radial of ROGEE here.

What app do you plan to use to display
both the chart graphic and the GPS position?

That shouldn't be a problem. I've already got a script for more powerful
computers to handle such displays. It could easily be modified to handle
the fuzzy areas of plates.

Generic moving map software could be used as long as the user realizes
that the display is inaccurate in some areas.
