[GEMPAK #PGI-541511]: GPANOT on a cross section?

Brian,

The cross section plots are x/y "graph" mode plots and not
lat/lon "map" mode plots, so gpanot will not be able to convert 
lat/lon into axis locations to overlay on gdcross output.

You could calculate x/y screen locations based on cross section 
relative locations (eg calculating a normalized 0,1 distance of
an aircraft lat/lon from the cross section cxstns location
and then plot those locations versus a scaled height, but can't be 
done automatically at this time given the tools at hand.

Are your aircraft locations in a GEMPAK surface data file?
