Re: [GEMPAK #YCE-717567]: Question on GDPLOT (well, 2)

Chiz,
Thanks for the info. I'll add _gif support (and improve our processing somewhat) tomorrow!
We didn't include the map in that display because we're using a web-mapping package (mapserver) to display the result. This will be an intermediate product 'til I'm happy with the netcdf data I'm producing from the MM5 runs, and start using the OGC Web Coverage Service for similar work. We've got maps of the region in the mapserver dataset, so we would prefer to use that as the two map datasets don't always correspond when we've tried something like this in the past. 

Our grid is an LCC 60/-101/30 grid with corners (via GAREA) as:
GAREA   23.84;-106.81;37.36;-84.1
I'd have thought that we'd have some blank (or black) data in this region but the image we're seeing isn't consistent with the reprojection geometry I'd expected for a CED result, so either I'm coffee-deprived or confused. I'll look at interpolating using GDDIAG. Thanks.
The scripts we're using and the .nts files are theoretically attached to this one. If they don't come thru, look on http://mesonet.tamu.edu/Ver/ for the files. 

Thanks!
See you at AMS.

Gerry,

I didn't get your .nts file attachments.

In answer to your question 1), there isn't a target in the gdplot2 Makefile to 
build a gdplot2_gif,
but, it is very simple to add this into the Makefile. I have attached an update 
for
$GEMPAK/source/prograns/gd/gdplot2/Makefile

Replace the current gdplot2 Makefile, and then build with:
cd $GEMPAK/source/prograns/gd/gdplot2/Makefile
make programs_gif
make clean

2) Your graphic doesn't have a map, so I'm not sure what you are referring to.
To define the display of a gridded data set using the CED projection, set the parameter PROJ=ced instead of DEF or whatever other projection you are using. 

If you want to interpolate your grid from a different projection to CED points,
you can do that using GDDIAG, such that a CED display of the grid will have the 
interpolated
point locations on straight rows/columns.

Note that anytime you display a grid in something other than its native 
projection, the
rows and columns will not necessarily look straight!

If you want to send me your .nts input, I'll see what you are doing,
