20040310: VAD display



Bruce and Robert,

Since you were involved in the original VAD discussion, I'll invite
you to download my GPVAD for testing.

Note that this program will display the NVW NEXRAD Level III product
which is just drawing command and line locations rather than actual
time/height values as is found in the RCM product. That is,
the NVW product contains drawing commands for lines, colors, vectors
to produce the picture, as opposed to an upperair type of SNCROSS plot
which would be more likely from the RCM.

I placed 2 files out on the download/gempak/contrib site (so far), 
a source and a Linux binary:
http://my.unidata.ucar.edu/modules.php?name=Downloads&d_op=viewsdownload&sid=9

To install the Linux binary, download the tarfile to your $NAWIPS
directory and unpack from there with:
gunzip -c gpvad_linux.tar.gz | tar xvf -

To build from source, unpack the source code tar file from $NAWIPS:
gunzip -c gpvad.tar.gz | tar xvf -

Then build with:
cd $NAWIPS/unidata/programs/gpvad
make clean
make all
make install
make clean

Run the program as "gpvad".

To specify a NEXRAD Level III file, you can either give RADFIL
the name, or use a template.

To use the NEXRIII template as defined in $GEMTBL/config/datatype.tbl,
as an example,

RADFIL =  NEXRIII|ILX|NVW
RADTIM =  current       
WIND   =  bk1
TITLE  =  1/-2/ILX VAD DISPLAY ~
PANEL  =  0                    
DEVICE =  XW                  
CLEAR  =  y                  
TEXT   =  1/1/1/hw          
CLRBAR =  1/v/cl/.05;.5/.3;.01
GEMPAK-GPVAD>


The NEXRIII template uses %SITE% = ILX and %PROD% = NVW
in composing the file template in this example. NVW is the
only valid %PROD% value.

See online help "phelp gpvad" for more info.
