Hi Kevin-

Thanks.

This is on our TODO list.  Figuring out what points in a 3D
radar file which is in range, azimuth and elevation are on
a lat/lon/alt line is a challenge.  Regridding the entire volume
is an option, but expensive.

>Another example of this is the cross section display ability =

Okay.

It's not on the TODO list, but in the back of my mind always.  There's
only 2 of us and it's just a matter of finding the time to add in a
new data source.

>Thanks for considering some of these suggestions. I understand if some =

Like I said, it doesn't hurt to ask (and I can't promise anything).

One thing we are working on for the next release is an improved drawing
control that will let you annotate the displays (text, lines, images,
and eventually fronts).  The shapes can be time dependent so they
will show up on particular frames in the animation.  This might
be useful in your work.
